I am making a game with allegro: typedef struct tagANIM { double clock; unsigned char *next; }ANIM; ANIM *anims; Then I load all the data into the anim structure (by malloc'ing ) its a basic linked list. ok then in some parts of my program I go like this: ANIM *t; t=(ANIM *)anims; do { t->clock++; [alot of code here] }while(!ENDGAME); Ok...heres the problem....everytime I run the program it gives me an error. I can trace it back to t->clock++, but if I remove the do/while loop...it works perfectly. (but I need the loop). If I fix one then the error is then loacted at another point in the program, but in a sub that has the same loop as above. I think its whatever statement that is right after the DO that will error. if I put t->clock++ before the DO loop wvwrything is fine. Has anyone ever experienced this? Denis Lamarche
