Program crashes after a few times

Error1312 · Post by **Error1312** » Sun Feb 15, 2004 2:22 pm

Hello.

I have some strange errors with either Visual C++ 6 and 7. The first 5 to 10 times I run my program, everything goes fine. After that, the DOS box with 'Irrlicht engine 0.4.2' pops up, but the program itself doesn't start. I have to restart my computer and then it works again for a few times.

Does somebody know what causes this problem? It's very annoying to restart your computer every time.

Thanks in advance

In most cases this is a driver problem. Update your drivers to the latest version and retry.

I have installed the latest drivers but the program still crashes after a few times.

My graphics card is a Geforce 4 Ti4200 so I don't think that's the problem. By the way, I only use Irrlicht to get my program fullscreen and to easily put text on the screen (Just for this project, of course), so I don't think my drivers could be the problem.

Have you installed other 3D-Applications on your pc, and they are all working 100% correctly? And what OS are you using? Maybe the application does not shut down correctly, I've heard that this is the case on Win95 on some machines with Irrlicht 0.4.2

you probably have resource leaks in your program. Sometimes it's worse than memory leaks cause there are some system-limited resources (like number of timers, window handlers, etc.)...

Anyway it's difficult to help if you just say something like "my program crashes from time to time"... Could you debug it a little. Is Irrlich window is created up to the crash moment or not? etc...

BTW, there is a good program BoundsChecker (AFAIK up to VC60 now), which tells you about all of your memory/resource leaks in a very convenient way... VC70 tells you about memory leaks at the end of the debug session (but it says nothing about leaks in dll,etc...) If you haven't modified Irrlicht dll than it should be fine to trust that info.
