c# multithreading abort finally
Everything I’ve read claims an abort on a thread will execute the finally block before ending from a ThreadAbortException. I wanted to confirm this so I can plan on how to handle some 3rd party code that can hang indefinitely. However the following test has me confused:public void runTest(DateTime deadline) {testThread = new Thread(() => {try {Console.WriteLine(“test thread started at ” + DateTime.Now.ToShortTimeString());while (true) { }}finally{Console.WriteLine(“test thread entered FINALLY

wcf proxy close wcf-client abort
Based on documentation and articles it is recommended to call Abort() on a client proxy if an unexpected exception/fault is encountered. See the following (simplified):MyServiceClient proxy = null; try {proxy = new MyServiceClient();proxy.DoSomething();proxy.Close(); } catch (Exception ex) {if (proxy != null)proxy.Abort(); }Is there any possibility of the call to Abort() throwing an exception itself? Should the call to Abort() be within its own try/catch?

delphi shutdown abort
I’ve got a program that’s having some trouble during shutdown, raising exceptions that I can’t trace back to their source. It appears to be timing-related and non-deterministic. This is occurring after all shared resources have been released, and since it’s shutdown, memory leaks are not an issue, so that makes me wonder if there’s any way to just tell the program to terminate immediately and silently after releasing the shared resources, instead of continuing with the shutdown sequence and gi

c# multithreading thread-safety using-statement abort
I’ve just finished reading “C# 4.0 in a Nutshell” (O’Reilly) and I think it’s a great book for a programmer willing to switch to C#, but it left me wondering. My problem is the definition of using statement. According to the book (p. 138),using (StreamReader reader = File.OpenText(“file.txt”)) {… }is precisely equivalent to:StreamReader reader = File.OpenText(“file.txt”); try {… } finally {if (reader != null)((IDisposable)reader).Dispose(); }Suppose, however, that this is true and that this

redirect handling abort
I have a system where users can post their own code. If the code generates any sort of error, I had hoped to deactivate the script, instead of crashing the system. That way they don’t have to fish out the script and delete it.So the user will have things inside these php tags…<?php //Random dangerous stuff that user can do, as he learns how not to blow stuff up… ?>So anything inside of those PHP tags that causes an error, I’d simply like to run a function that deactivates that script (

c++ c gdb abort raise
I’m trying to debug one of my crashes and it seems to be caused by the abort raised from some where, and my gdb is not giving the caller details instead just shows few frames in the callstack. Any suggestions would be most welcome in debugging this issue.(gdb) bt #0 0x76453fc4 in raise () from /lib/libc.so.0 #1 0x7644d654 in abort () from /lib/libc.so.0 #2 0x7644cc4c in ??

c++ exception gdb g++ abort
This question already has an answer here:Run an Application in GDB Until an Exception Occurs2 answersIn a non-trivial program, there may be any number of exceptions, being thrown and caught. While this is intended to prevent crashes, it makes debugging harder (I debug with gdb) since I don’t get to see the point (and its backtrace) where the exception was thrown when debugging the binary unless I identify the line and introduce a break point.So, to facilitate analysis, it would be useful to tell

I’m having diffuculty with the example below, the last line is producing an “abort has been called” error.

c++ vector abort
I’ve written a program that uses a vector and a map. When i run it, i get this following error message: lru: malloc.c:3552: munmap_chunk: Assertion `ret == 0′ failed.

Here’s my code: #include <stdio.h> #include <stdlib.h> #include <iostream> #include <vector> #include <map> #include “byutr.h”using namespace std;///////////////////////////////////

data abort
When i am using function name as variable mistakenly it is causing abort.condition is like this hello() { }if(!hello) //this is crashing { }As per my understanding this code should not crash as the function name is a valid address. Also because of this my data segment is getting corrupted( not able to see any variable in crash inspect).

ios multithreading exception exception-handling abort
I have not found documentation that is consistent with my experience.What I want is a good way of handling Uncaught-Exceptions in a background thread. This “way” should let the app crash, but perform some very basic operations before crashing (e.g. saving a value to UserDefaults so that it can be examined on next startup; plus logging). On the main thread, I just set up an uncaughtExceptionHanlder and this works fine. However, on a background thread – executed as an NSOperation on an NSOperation

vb.net crash abort
I have a program up and going that interacts with hardware, but I need to test the case of when the program crashes/aborts or anything to cause the program to exit unnormally to see what state is set to the hardware when the software crashes. In C++ I saw a post about using an abort() call (What is the easiest way to make a C++ program crash?), but I am unsure what the VB equivalent of that would be. The closest I have come is while debugging, to press the Stop Debugging button, but I think ther

.net multithreading processes terminate abort
I’m trying to gather a complete listing of the reasons a .NET process or thread to terminate, even though the main() method is guarded by a try…catch clause.One such reason is Thread.Abort() (unless you call Thread.ResetAbort). Do you know of more reasons?

c++ exception pthreads terminate abort
So my understanding of both pthread_exit and pthread_cancel is that they both cause an exception-like thing called a “forced unwind” to be thrown out of the relevant stack frame in the target thread. This can be caught in order to do thread-specific clean-up, but must be re-thrown or else we get an implicit abort() at the end of the catch block that didn’t re-throw.In the case of pthread_cancel, that happens either immediately on receipt of the associated signal, or the next entry into a cancel

c++ exception-handling static-libraries abort
I am compiling my program with a 3rd party library. That library contains an error callback if an error occurs internally. Inside that error callback I am throwing an exception and I have a unit test to verify that when I do something invalid that the exception is thrown. This all works beautifully in Windows, but when I test this in linux (fedora) I am getting an abort from an uncaught exception.I tried wrapping my call directly with a try-catch block but no luck.

c++ c io abort
Is there a need to explicitly flush output streams before calling abort() to avoid loss of output?As I understand, with stderr there is no buffering, so calling abort after output to stderr/cerr should be ok. How about stdout/cout, or files that I open?PS. I am working in Linux environment (if it matters).
