You're probably seeing a known bug in gdb where it no longer works well
when run from a console window.  There is a race where gdb tries to get
tty information from a stopped cygwin process.  Although I didn't
introduce the problem, I have tried to fix it from time to time without
much luck.

Debugging from mintty will probably work better.
