I working on some code that draws 2 images from 2 separate surfaces together onto another surface and then draws this surface to the screen surface straight after. I'm using 640*480*8 with a set palette. All surfaces have been assigned the same palette. This works the first time round but when it attempts to do it a second time, it crashes the program.



Src.X:=0; Src.Y:=0; Src.W:=32; Src.H:=16;
Dest.X:=0; Dest.Y:=0; Dest.W:=32; Dest.H:=16;
SDL_BlitSurface(SrcSurf1,@Src,DestSurf,@Dest);
SDL_BlitSurface(SrcSurf2,@Src,DestSurf,@Dest);
SDL_BlitSurface(DestSurf,@Src,Screen,@Dest);
SDL_FLIP(Screen);
SDL_BlitSurface(SrcSurf1,@Src,DestSurf,@Dest);
SDL_BlitSurface(SrcSurf2,@Src,DestSurf,@Dest);
SDL_BlitSurface(DestSurf,@Src,Screen,@Dest);
SDL_FLIP(Screen);


[EDIT] I've just written a test bed program and it works on this so I guess it must be a problem elsewhere. Disregard this post.
