Try running "ulimit -c unlimited" in the shell before running the test
(from the same shell).  After it aborts it should dump a core file,
which you can then inspect using "gdb ./python core", to which "bt"
will give you a stack trace ("backtrace").

On a minor note, I'd suggest running "./python -m test.regrtest"
explicitly, rather than "make test".  The latter runs the test suite
twice, deleting all .pyc files before the first run, to detect
problems in their creation.
