Hi everybody!
   I am programming a game with DJGPP 2.0, and I'm finding it is a realy
*great* tool. I have currently written 2500+ lines in C++/Asm, and had no
problem (except for my own bugs ;). But now I am facing a strange behaviour
with my program: If I compile it *without* optimizations (-m486 -O3), it
crashes with a page fault after exiting the game (I mean: you quit playing,
and then it dumps out a GPF, no problem *while* playing). I find no problem
when compiling with -m486 -O3, anyway.
I've debugged the generated code, and I've found that the problem is GCC
not passing the correct arguments to some functions. I call the function
with the correct parameter (made sure of this), but it gets a wild one!
I stopped using the nearptr feature, as this is dangerous, but the problem
didn't went away...any clue???

Yes, I am using the last version of CWSDPMI and those things...

Any help would be appreciated.
Thanks in advance.
