I think the spurious Ctrl-M characters appeared with Leopard and weren't
present in Tiger but, in any case Apple GDB has it's own behaviours tailored
for their Xcode application.  For best results, and no ^M characters, download
the latest (7.0) FSF gdb (http://sourceware.org/gdb/download/) or checkout
from the CVS repository (http://sourceware.org/gdb/current/) which both build on
Darwin.

I have closed this report since FSF gdb fixes this problem and support of Apple gdb
probably isn't an FSF priority.
