Yes, it seems to crash in the collision routine.
So, now every time you do a SPRCOLL or ANIMCOLL, (write a wrapper function: mySPRCOLL), please STDOUT the parameters you pass. Then with these parameters make a small program that loads the 2 sprites/animations and does only this one ANIMCOLL call. It will surely crash as well. Please post me the code and the 2 files then.
I'm so sorry.
