Actually, here's a full stack trace from gdb (when running /bin/cpan):
#0 0x6104bfb6 in cygwin_getprotobynumber (number=17236) at /usr/src/cygwin-cvs/src/winsup/cygwin/net.cc:548
#1 0x6107589f in _sigfe () at /usr/src/cygwin-cvs/src/winsup/cygwin/cygserver.h:82
#2 0x0022ee18 in ?? ()
#3 0x100ace0c in cygperl5_8!Perl_free_tmps () from /usr/bin/cygperl5_8.dll
#4 0x10071e19 in cygperl5_8!Perl_runops_standard () from /usr/bin/cygperl5_8.dll
#5 0x100076f5 in perl_run () from /usr/bin/cygperl5_8.dll
#6 0x004011d6 in cygcrypt-0!crypt ()

#8 0x61005b93 in _dll_crt0 () at /usr/src/cygwin-cvs/src/winsup/cygwin/dcrt0.cc:915
#9 0x00000000 in ?? () from
Frames #0 looks bogus, and #1 seems to have a wrong file/line number.
Some sort of stack corruption?
Unfortunately, I don't have a debug build of Perl (and no time right now
to create one). Any takers?
