Yes.  I was getting NTVDM errors when I was trying to generate a cross
compiler (unfortunately, I didn't hear anything regarding this):

    http://www.cygwin.com/ml/cygwin/2000-12/msg00059.html

In this instance, it appeared related to forking the compiler for a
configure test.  The other time I saw these NTVDM errors were when
configure was trying a vfork() test (also when I was trying to build
another cross compiler.)  In both cases, the bug could be reproduced
roughly 90% of the time.

If I had to guess, I'd say there's some sort of issue with the
fork()/vfork() implementation.  Unfortunately, I didn't have the time
then, but I might be able to help you track this error down this time.
The only thing I have to offer is the fact that I have an old copy of
SoftICE for NT, so if I can reproduce this bug (and find my copy of
SoftICE), I might be able to contribute.
