Aliens crash problem under win32/VC++ 6.0


Ive been trying to run the demo game aliens under vc++ 6.0 (of course it
compiles fine under Linux), but after compiling, linking, etc, the game
gpfs. Ive traced it down to it crashing during the
SDL_LowerBlit(blits[i].src, blits[i].srcrect, screen, blits[i].dstrect);
call in UpdateScreen. Im using all the current SDL* libs, with the right
files attached to the project, etcetc (Im pretty sure project is setup
right, the background.gif gets shown, then the stupid gpf window pops up).
Any ideas on this?
