homm3 debug session

Attached is a log from a homm3 debug session.

For me it looks like the exceptions happen in IWineD3DBaseSurfaceImpl_Blt on an
access to dbuf (e.g. memcpy(dbuf, sbuf, width); - ~line 1240 in
surface_base.c). It could also happen on other accesses to dbuf in
IWineD3DBaseSurfaceImpl_Blt.

The exception doesn't happen all the time, I guess only when dbuf is a dib
section which is created/filled by X11DRV_XRender_SetPhysBitmapDepth() (Any
idea how to check that?). If I comment the
if(!X11DRV_XRender_SetPhysBitmapDepth()) in dib.c then no exceptions are
thrown. The game runs fine with these exceptions and disabled sound. My guess
is that the combination of the exceptions and the "sound bug" let the game
crash. One alone let the game run fine.
