Strange Crash in Direct X init

[Robert Lunnon]

I have a strange crash in thread creation with a program called little fighter II (Which is downloadable off the internet)
 LF2 Spawns a Thread in User_DirectDrawSurface_Construct  (below) and when created the thread creation call 
crashes in a mutex_lock. Strange thing is the same thread creation calll in eudora3.2 succeeds although 
there the thread is created to service Asychronous Winsock calls. In the eudora case the Thread is created much later,
after the window is up and dispalyed.

Can anyone hazard a guess as to what is happening here ? I am at a loss to explain why the 
same call should succeed in one place and fall over in another

See below for a partial debug session transcript of the code leading up to the segv fault
the program will fall over during the call to _lwp_create.

Bob...

The program being debugged has been started already.
Start it from the beginning? (y or n) y
