C++ :: Debugger Crashes When Break Point Is Inside A Function

So, I have this code:

...
MakeTexture((char*)ilGetData(), ilGetInteger(IL_IMAGE_WIDTH), ilGetInteger(IL_IMAGE_HEIGHT));
...

And it compiles fine and, supposedly, works fine too, but when I try to put a break point inside the MakeTexture fuction gdb just goes crazy, it freezes and starts alocating memory until it reaches like 30+ mbs, and after that codeblocks freezes and I have to terminate the gdb process to return everything back to normal.

Now, another weird thing is that this only happens if I pass (char*)ilGetData(), if I pass something like NULL to the function, this doesn't happen.

Oh, also, the MakeTexture function is this:

int MakeTexture(char *pxData, unsigned w, unsigned h)
{
return 0;
}
