Searching the mailing list archives would show that this question has
already come up (several times this week, in fact).  The fault is
EXPECTED, and HARMLESS - just continue on debugging from that point.
Basically, inside cygwin functions, cygwin installs its own fault
detection handler, and pthread_key_create intentionally faults on the
first time the key is used.  It is just a matter of teaching gdb that this
fault is expected and will be covered seamlessly by cygwin.
