The program has unexpectedly finished with code 1073741819
-
I have read many threads regarding the program crashing with code 1073741819 but in most cases it's the pointer or memory allocation problem. My application was running smoothly. I made no changes and when I randomly ran the application, this error was thrown. I read many threads on how to solve it but it didn't help. Reopening Qt solved it. Today I have the same problem again. I tried restarting Qt but the problem persists.
PLEASE HELP!
I don't know how to setup a debugger or even install one. And I can't post my code because I have more than 8 classes and the code is huge.

Yes you are rigth, this is a allocation problem. When i get same error debugging helps me and every time it was a buggy code. What toolchain you use? Why cant debug it? Any way you can put qDebug() messages into a suspicious parts of the code.
-
That's the thing. The application works well. No issues, no errors. Suddenly it starts throwing this error so I have NO idea which part of the code is buggy.
Btw, an hour after I posted the question, my app started working. It's mysterious. But I want to be prepared for the next time it behaves unexpectedly -
If you can't debug, you have to check that every allocation is associated with a deallocation (That can be partially done using a static code analyzer).
If you're on linux/os x (but the error code makes me think you're running Windows) you might want to run your application through Valgrind.
-
The application is running fine for now. I'll give Valgrind a shot and mark this question solved if it works out for me.
Thanks for your reply.
EDIT: I'm working on Windows and I just realized Valgrind is for Linux. I'll look for an alternative

I haven't used it myself, just shared it since it runs on windows as well.
