First of all, the test case is great! Thanks.
Running 'run-test.sh' can expose the problem on GDB trunk, but a little bit
differently,
---------------------------------------
$ ./run-test.sh
make: Nothing to be done for `all'.
Process ./bar created; pid = 26114
Listening on port 7777
Python Exception <type 'exceptions.ImportError'> No module named gdb:

`/usr/local/share/gdb/python'.
