Rob,
I built the DEBUG version fo all the libs in X, and twm. I still get same
results from gdb.  info threads and info locals does not tell me much.  I am
not sure from where first line of bt is coming.... perhaps some Windows
dlls, e.g. kernel32 for which debug symbols are not available.  Anyhow,
below is the cut and paste from gdb.

Can you also do 
info threads
info locals
 
Thanks,
