Summary: All: Module player unstable, with Protracker

Initial Comment:
ScummVM 0.11.0svn (Jun 15 2007 14:20:12)
Compiled under mingw with GCC 3.4.5
Running on Windows XP Media Center 2005 Edition
English Amiga of Nippon Safes (Multi-Language).
English Amiga CD32 of Simon the Sorcerer 1.

The current module player in ScummVM doesn't seem stable,  
as I often get random crashes in Amiga versions of games, especially when switching music. The Amiga versions of these games, specifically use Protracker modules.

I thought the issue might be specific to the AOGS engine, when using Amiga versions. But I produced similar crash in Parallaction engine, when trying out the Amiga version of Nippon Safes.

GDB always reports similar heap corruption:
Program received signal SIGTRAP, Trace/breakpoint trap.
0x7c901231 in ntdll!DbgUiConnectToDbg () from ntdll.dll
(gdb) warning: HEAP[scummvm.exe]: 
warning: Heap block at 031894C8 modified at 03189B6A past requested size of 698

But doesn't give a useful backtrace, due to the heap corruption.

When I tried the games under ScummVM in Topologilinux, I'm unable to reproduce the crashes and Valgrind doesn't report any issues. I don't have sound support under Topologilinux though, so that could be why.
