You don't say what version of Emacs you are using.  If it's 22.1, or later,
you can see in the minibuffer that gdb runs with the option "--annotate=3".
Your script probably interact with Emacs in the same way as gdb would
if you removed this option.

Assuming your script doesn't filter the gdb output, you probably just need to
ensure that it runs gdb with the above option.
