Ah, yep - "rm python-gdb.py", "make" cleared up those remaining ".function" failures. The makefile could probably use a Modules/Setup.dist vs Modules/Setup style warning when libpython.py is newer than python-gdb.py to help prevent anyone else getting caught by that.

I still get one failure after that, even after a "make clean", "make", "./python -m test.regrtest -v test_gdb". Given the "unable to read Python frame information" embedded in the result on my machine (64-bit Kubuntu 9.10), it is probably related to the current issue.

The remaining failure:
