You can't have the fancy UI with gud-gdb.  My suggestion was an
attempt to see if the problem is caused by the use of the GDB/MI
interface.  It sounds like it is.

Does it help to use "M-x gdb" from "emacs -Q"?  If in "emacs -Q" you
see no problems, then look into your customizations or your site init
file for the reasons for the hang.

If that doesn't help, I'd suggest to upgrade to the latest GDB (7.8.2
was just released) and to the latest Emacs 24.4.  The reason is that I
don't see any problems with those latest versions in your usage
scenario.

If upgrading doesn't help, please submit a full bug report with all
the details using "M-x report-emacs-bug".
