gtkmm causes gdb to hang...

[jeff jeffplummer com]

I am using codeblocks (www.codeblocks.org) and gdb and I'm having some
trouble with gtkmm.

when I try to single step into my 3 line program it locks up using 100% of
my cpu.

Gtk::Main kit(&argc, &argv);
Gtk::Window window;
Gtk::Main::run(window);

(Note: I've single-stepped through other programs in codeblocks and gdb,
so I'm pretty sure they are configured correctly).

Looking at my gdb log it says
> directory D:/Profiles/P56711~1.GDD/Desktop/temp/
> file DesignTool2.exe
> set args --sync
> delete
> set confirm off
> set new-console on
> set disassembly-flavor intel
> run


Any ideas?  I'm coming from a visual c++ background, and never really had
problems with a debugger.

thanks,
Jeff Plummer
