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. -- Dario Alcocer -- Sr. Software Developer, Helix Digital Inc. alcocer AT helixdigital DOT com -- http://www.helixdigital.com -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
