You haven't provided any information about which GDB version you are
running, etc.  You are also using a completely closed platform, and
Apple have dropped support for GDB some time ago, so this is their
problem...

Nevertheless, it seems the problem is that you are using an old version
of GDB.  This bug:

<https://sourceware.org/bugzilla/show_bug.cgi?id=11488>

apparently reports the same problem, and it has been fixed in 2010.  If
you can upgrade the GDB version that is running on your device, that
would probably solve the problem.  Other than that, I don't know.
