excerpt of traces with several WINEDEBUG settings

The common aspect between mcm2 and Alien Nations seems that havoc breaks out
soon after amstream:IDirectDrawMediaStreamImpl_GetFormat().
Both applications do not manage to play their intro video (others do).

The error messages (see attachment) suggest that wine becomes confused by
garbaged memory data. Perhaps a race condition is involved as well, as there's
an extreme sensitivity on WINEDEBUG settings:

A default trace without $WINEDEBUG yields (among others):
err:d3d:resource_init Out of memory!
but Alien Nations nevertheless runs successfully - without video.

WINEDEBUG=+all,-dbghelp_dwarf,... 2>/dev/shm/v.log
 yields no such err: line at all.

WINEDEBUG=+amstream,-dbghelp_dwarf,-heap,warn+heap,-gdi,-dsound,+quartz,+tid,+seh,+ole
 yields a crash after a few errors which look like illegal arguments were
supplied to ddraw functions:
err:ddraw:IDirectDrawImpl_CreateSurface Unknown Z buffer bit depth
err:ddraw:IDirectDrawSurfaceImpl_QueryInterface No interface
err:ddraw:PixelFormat_DD2WineD3D Unknown Pixelformat!

(The Alien Nations is easier to trace+all than MCM2 because the latter does a
million irrelevant +relay and +nls calls)
