Please look at the GDB manual, which describes what the argument to
this command should be.

Sourcery G++ Lite is not supported; if you continue to have difficulty
configuring Linux debugging, you may want to consider an evaluation of
our Standard Edition or Professional Edition product for access to
support.

No modern compiler uses this frame layout.  If you upgrade to the
latest Sourcery G++ release, you can use the libc backtrace()
function, but it's never as reliable as GDB.
