Hi all,

I'm running into problems debugging c++ under emacs. When I start the
debugging command:

M-x gdb --annotate=3 myprogram

The gdb shell does not prompt. Instead it stuck after showing "(gdb) Current
directory is ~/programs/small/" as pasted below. I can't type any debug
command then... However the status bar shows no error messages. Does any
body know how to fix it? Thank you!
