I don't know if it's related, but the newer versions of the Cygwin runtime
use a function from Kernel32.dll (IsBadWritePtr) that produces (and later
handles) an intentional SIGSEGV. Since the SIGSEGV is handled, it's not
seen outside of gdb. Did you try continuing a few times? For me (on
Win2k), 4 continues do the trick, and the program completes normally.
