  c++ memory pointers polymorphism bad-alloc
  I need some clarification on an issue I don’t quite understand. Using the two scenarios that follow, I would have thought that the amount of memory allocated would roughly be the same. However, scenario 2 gives me a bad_alloc exception after a while and appears to be chewing up memory like crazy (using Window’s Task Manager as a proxy for the amount of memory allocated to the process). The following is compiled on Windows 32bit using MSVC10. Say I have following base class:template<class T&

  c++ c debugging gdb bad-alloc
  I have a program failing with:terminate called after throwing an instance of ‘std::bad_alloc’what(): St9bad_allocI imagine it’s something to do with malloc/free, but I don’t know which one.What breakpoint can I in gdb set that will break on the error so that I can view a stack trace?The program is a combination of C and C++, compiled with gcc 3.4.2.

  c++ arrays new-operator bad-alloc
  I’m having prblems with my C++/openGL program.at some point of code, like these(it’s a constructor):MyObject(MyMesh * m, MyTexture* t, float *c=NULL, float *sr=NULL, int sh=100){ texture=t; mesh=m; subObjects=NULL; texCoords=NULL; if (texture!=NULL){texCoords=new float[mesh->numSurfacePoints*2];the new throws an std::bad_alloc exception. it’s the same at another place. is it possible, that i ran out of memory? i dont think so, so if you could help me, i would be glad! bye!

  c++ arrays new-operator bad-alloc
  I’ve debugged my other problem back, to the MyMesh constructor. In this code:if (hollow) {numTriangles = n*8;triangles=new MyTriangle[numTriangles];if (smooth) numSurfacePoints=n*8;else numSurfacePoints=n*12;surfacePoints=new SurfacePoint[numSurfacePoints]; }else {numTriangles = n*4;triangles=new MyTriangle[numTriangles];if (smooth){numSurfacePoints=n*4;surfacePoints=new SurfacePoint[numSurfacePoints];surfacePoints[n*4]=SurfacePoint(vector3(0,0,1),vector3(0,0,1));surfacePoints[n*4+1]=SurfacePoin

  c++ linux memory-management map bad-alloc
  I am running a C++ program that involving building inverted index on red hat linux 64 bits. My invert index is defined as map<unsigned long long int, map<int,int> > invertID; and I got this error where it crashes randomly, with what(): St9bad_alloc.Each time of the crash is different. Sometimes, I got 100,000,000 keys and it’s still running a while more. Sometimes, about 80,000,000 keys and it already yell out the error.Googling around, I found that this error may come from new, but

  xml-parsing crash mex bad-alloc g++-4.7
  I have an high level problem (I believe) that I will try to explain;My development platform is: 64bit Ubuntu 12.04 LTS and MATLAB 2013b with GCC/G++-4.7 libraryI am trying to create a MATLAB interface by coding a MexFunction using gigantic C++ library previously developed. For the tests I previously build and MexFunction only using and parsing XML files as inputs where paths are hardly defined within the function (for simplification and debugging), and I am not passing any input and output with

  c++ stl struct priority-queue bad-alloc
  I am working on a query processor that reads in long lists of document id’s from memory and looks for matching id’s. When it finds one, it creates a DOC struct containing the docid (an int) and the document’s rank (a double) and pushes it on to a priority queue. My problem is that when the word(s) searched for has a long list, when I try to push the DOC on to the queue, I get the following exception: Unhandled exception at 0x7c812afb in QueryProcessor.exe: Microsoft C++ exception: std::bad_allo

  c++ stl priority-queue bad-alloc
  I am writing a query processor which allocates large amounts of memory and tries to find matching documents. Whenever I find a match, I create a structure to hold two variables describing the document and add it to a priority queue. Since there is no way of knowing how many times I will do this, I tried creating my structs dynamically using new. When I pop a struct off the priority queue, the queue (STL priority queue implementation) is supposed to call the object’s destructor. My struct code ha

  c++ mysql mysql-connector bad-alloc
  I’ve been trying to hook up to my own locally hosted MySQL database with the MySQL/C++ Connector package. The lines that are really giving me a problem are:driver = get_driver_instance(); auto_ptr < Connection > con (driver -> connect(“tcp://127.0.0.1:3306”, “root”, “root”));Hitting the 2nd of the two lines gives me a memory allocation error. Here’s the readout from the debugger.HEAP[mySQLTestApp.exe]: Invalid allocation size – CCCCCCD0 (exceeded 7ffdefff) First-chance exception at 0x7c

  c++ segmentation-fault bad-alloc
  I have a program that implements several heuristic search algorithms and several domains, designed to experimentally evaluate the various algorithms. The program is written in C++, built using the GNU toolchain, and run on a 64-bit Ubuntu system. When I run my experiments, I use bash’s ulimit command to limit the amount of virtual memory the process can use, so that my test system does not start swapping.Certain algorithm/test instance combinations hit the memory limit I have defined. Most of

  c++ hash linked-list bad-alloc
  I am doing a hash set project for school. I have an array of type “LinkedList” used for chaining. I wrote my code on Mac and compiled with clang++, everything runs and works fine (with memory leaks but I will fix those). The problem that I am having is compiling on Ubuntu Linux with g++ I get a bad alloc error. When run in valgrind it says conditional jump or move depends on uninitialised value(s). And says the error is coming from the following section:LinkedList<ItemType>* table; . .

  c++ bad-alloc
  I am working with a program somebody else created. I have quite some experience with coding, but not all that much with coding in C++, so I’m doing a lot “learning by doing” here. So the program seemed to be stable, I started my work on it, which mostly included doing small modifications in small parts of the program. Recently I did some performance optimization, which also seemed to be stable, but 2 days ago I changed something and kept getting crashes. So I reverted my changes and still got t

  c++ vector bad-alloc
  This program strictly reads only alphabets, and pushes back to the vector as so. However the text file is just like any other text file.I have encountered this STD bad alloc exception and is as follows.char keyArray[5][5];keyArray[0][1] = ‘a’; keyArray[0][2] = ‘b’; keyArray[0][3] = ‘c’; keyArray[0][4] = ‘d’; keyArray[0][5] = ‘e’; keyArray[1][1] = ‘f’; keyArray[1][2] = ‘g’; keyArray[1][3] = ‘h’; keyArray[1][4] = ‘i’; keyArray[1][5] = ‘k’; keyArray[2][1] = ‘l’; keyArray[2][2] = ‘m’; keyArray[2][3]

  c++ vector genetic-algorithm bad-alloc
  I’m writing a genetic algorithm for which I’m creating a “crossover” operator as a class object that is passed the two parent “chromosomes” Because the input and therefore the output chromosomes are variable lengths, my idea was two divide the input chromosomes and place in a sort of storage class variable, then resize the input chromosomes, and then finally refill the input chromosomes. I’m getting a bad_alloc error, however. If someone could spot my error I’d very much appreciate the help.T
