Summary

0002657: SIGSEGV in RAI (cRAI::UnitDamaged)

Description

U might or might not be a valid object.
both U->ud and U->udr were 0x0, which would an invalid state.
some other vars had strange values, like CloakUI = 0x5e.
I was not able to find out how this might have happened, though.

Additional Information

Program received signal SIGSEGV, Segmentation fault.
