Your binary is in... I forget what it's called -- oh, "mach-o"

Our (fsf) gdb does not know how to read that file format. And it
would be a huge job to port over the changes in apple gdb that tell
it how to read mach-o files (besides the fact that they are "fat"
files, or at least potentially might be). m
The Mach-O part does work in 7.0, thanks to Tristan and AdaCore
(check out gdb/machoread.c). I don't think fatness-handling is
there, although at the Xcode level one has to specifically ask for
fat builds anyway, so one could avoid that particular obstacle and
thus be well-positioned to smack one's face into the next wall. :-)
Right. The work-around is not to build fat binaries.
Current FSF gdb can't handle fat executable. I am not sure that we
want to implement this, but feel free
to ask. However gdb handles fat objects such as dylibs.
