What you're doing seems correct from your description. This sounds like there's some problem with the debug info.
Make a file called .gdbinit in your home directory, and put in it:
set verbose on
In the debugging pane of Xcode Preferences, there's a setting to generate the debugging log. Turn that on as well.
Then run your debugging session to the point of failure. Then file a bug including the log file. We'll be able to tell from the log file which file gdb was reading when this error occurred, and then if you don't mind, get a dump of the dwarf from that file and have a look to see what is wrong.
Thanks,
Jim
