I had to revert to the older version.All, I updated gdb to 7.3.50-2 and I can no longer run M-x gdb under emacs inside rxvt (gdb core dumps). Reverting back to 7.3.50-1 and it works. The executable being debugged is built with gcc 4.5.3 and gdb under rxvt and ddd works. Running M-x shell (/bin/sh) gdb also works. Running M-x gdba fails identically to M-x gdb. The odd thing is that after "Reading symbols ... done" nothing is typed and the "Debugger segmentation fault (core dumped) occurs w/o typing a key.

Debugger segmentation fault (core dumped)
I can confirm this. Bug M-x gud-gdb seems to work fine. I realize, however, that it may not give you the graphical interface that you'd like.
Notice that when you use M-x gdb, emacs calls gdb with the --annotate=3 option. A google search suggests that this option is obsolete. I don't know if that's part of the problem or not. I can run gdb with that option outside of emacs and it doesn't segfault.
Has anybody figured out what might be causing the issue?
