The stackdump isn't very useful unless there's debug information
available, which isn't for 1.5.18.  Would you mind to try the same
with the latest snapshot DLL,

http://cygwin.com/snapshots/cygwin1-20050916.dll.bz2

and report back if either the problem is solved or if not, send the
resulting strace?


Thanks,
Corinna
