gdb broken inside emacs (again? still?)

[Ryan Johnson <ryan.johnson@cs.utoronto.ca>]

Hi all,

Attempting to run gdb inside emacs with an executable file name argument 
(with or without --annotate=3) causes it to seg fault (no surprise, 
known issue). Running just `gdb' from emacs allows it to initialize, but 
attempts to load a file or indeed perform any command hang until a 
double-^C cancels the attempt (reporting "C-c C-cquit"). Ironically, 
even `quit' hangs, so you have to use ^D to exit. Debugging anything 
within emacs is thus completely impossible at this time. I've tried with 
a home-compiled gdb (same version) with no better luck. I'm building an 
emacs-23 from scratch, but I'm pretty sure I've already tried that 
before, without any conclusive improvement.

I know this has come up before, and that it has been "resolved" before 
for me and for others, but it keeps recurring (usually whenever I 
actually need to debug something) and I can't find any reliable way to 
make the problem go away.

Do the latest snapshots contain changes which should fix the problem?

I'm on an win7-64 system, running the 13 Oct dll snapshot, after a 
rebaseall. Relevant package versions are below (setup.exe doesn't 
advertize any newer ones):
> binutils                    2.22.51-1
> gcc4                        4.5.3-3
> gcc4-core                   4.5.3-3
> gcc4-g++                    4.5.3-3
> gcc4-java                   4.5.3-3
> gdb                         7.3.50-2
> emacs                       23.3-3
> emacs-X11                   23.3-3

Thanks,
Ryan
