IPHONE: Monkey2 crashes in alley

Reported by: lordhoto Owned by: wjp
Priority: normal Component: Engine: SCUMM
Version: Keywords:
Cc: Game: Monkey Island 2


Tested with: 1.4.1 and latest master (b71dffafbe438a5cea887ae3f72ef76dd5d00cd9) On: iPhone 3G 8GB

When entering the back alley on Phatt Island ScummVM just crashes. This happens nearly all of the time, once or twice in over 30 tries it worked though.

I attached a savegame of the German DOS version. It can also be reproduced with the English version via boot param 667.

(Partly) symbolicated crash log for the thread crashing with a SIGSEGV:

I tried fuzzie's suggestion and disabled the ARM assembly. Afterwards I couldn't reproduce the crash anymore. So I suspect there might be some memory corruption going on there. I will try whether I can track it down to one specific ARM assembly feature.

It turns out the crash starts to happen, when I enable USE_ARM_COSTUME_ASM, so the problem is probably somewhere in ClassicProc3RendererShadowARM.
