Hi there,

I've set up my own GU homebrew. I tried to clear all instances I've initiated. However, sometimes the PSP crashes where I guess the root cause may be memory leaks. Is there a possability to detect memory leaks ? I'm using minpsp and eclipse as development environment.

Thanks for any hints...

Regards

Good programming prevents memory leaks.

Memory leaks do not cause program crashes, unless your program comes to the point where it trys to allocate more memory which then fails and your program not handling that case properly.

If you are really concerned about memory leaks, a debug memory manager will help you detect those. One can be found on my devblog, which is an C-Version of the C++ memory manager by Paul Nettle.

Other than that, we cannot help you with your problem, as we don't have enough information.

You can also use mmgr to look for memory leaks if you still believe that is the cause.

Is there anything like a compile time garbage collection warning system?

It's cool you do not have to listen to me or Raph. We both answered this question.

Oh, cool thats exactly what mmgr is. I has no idea. Figured it was some kind of runtime debugging tool (which I normally couldn't be bothered to setup).

It has a few functions. But it basically can log every malloc/calloc and it can also catch memory leaks by watching the pointers handed out via these functions. I have not used it in a while, but I think you could alter some of the code,if it doesn't already have callback support, to cause a callback situation to form a sort of error handler to maybe go back and fix the problem, or reallocate the variable with more data.
