You will only get the red dot if you leave the gdb annotation level at 3.
This is a new mode in CVS Emacs that has many other features as described
in the accompanying Emacs manual (info pages). Setting the level to 1
just gives you the old mode.

"hello, world" is presumably output by your program. help-gnu-emacs
(or related) is for released versions of Emacs. You are more likely
to get an answer to your question if you post it to:

emacs-pretest-bug@gnu.org

with a reproducible testcase.

With CVS Emacs (currently 22.0.50) this list gets automatically selected
with M-x report-emacs-bug (on the menu-bar Help->Send Bug Report...)

Probably not.
