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. :-)

Stan,
I am puzzled about the fact that the current x86_64-apple-darwin10
build of FSF gdb 7.0 is unable to load i386 binaries like x86_64 gdb
can under linux. Do you think this should be possible without
resorting
to fat-binaries for darwin?
That's unexpected. It least it worked in the past. Will try to fix
that.
Tristan.
