So the idea is that it should be possible to get the last GDB version
provided by Apple (this was GDB 6.3.x with Xcode 4.x I think), bring the
core dump handling code under FSF copyright due to the blanket
assignment, and port it to the newer GDB?

The latest GDB binary I have from Apple is GNU gdb 6.3.50-20050815
(Apple version gdb-1824) (from Xcode 4.6.3).  It looks like the source
for this version is available here:

http://www.opensource.apple.com/tarballs/gdb/gdb-1824.tar.gz

For now maybe I'll just build this version myself; it doesn't have all
the latest GDB goodness but it's got to work better than LLDB.
