Ok, I can reproduce this on WinXP Pro SP1. The last few lines of strace
before the exception[*] show a read call that executes normally, and then
a SEGV. Someone with a debug version of Cygwin should be able to trace
through this in gdb.

In the future, please *attach* the output of cygcheck instead of including
it inline, to avoid false positives in archive searches. Thanks,
Igor
