Subject: bug#9767: 24.0.90; gdb initialization on Cygwin
Date: Sun, 16 Oct 2011 12:02:59 -0400

When I start a debugging session with M-x gdb, initialization doesn't
appear to complete.  I don't get the "(gdb)" prompt, and the mode line
continues to say "initializing".  If I press Return, I get the prompt
and the mode line changes to "ready".  Everything works fine after that.
This seems Cygwin-specific; it doesn't happen on GNU/Linux.

I've checked that all the strings that emacs sends to gdb during
initialization (via gdb-input) do in fact get sent.  And I've tried
sending those same strings to gdb outside of emacs (except for
"-inferior-tty-set..."), and nothing strange happened.  In particular, I
did have a "(gdb)" prompt at each stage.

Does anyone have any suggestions as to what might cause this or how I
can debug it?  I don't have any experience with elisp debugging, so I
would appreciate a few pointers to help get me started.

Thanks.

Ken
