[issue21166] Bus error on "AMD64 FreeBSD 9.x 3.4" buildbot

Interestingly, I note the following lines from the gdb log:

#5  0x0000000801ae1e99 in PyModule_Create2 () from /usr/local/lib/libpython3.4m.so.1
#6  0x0000000801840de8 in PyInit__heapq () from /usr/local/lib/python3.4/lib-dynload/_heapq.so

I had installed Python 3.4 just prior to Victor reporting the issue.

If its at all relevant, Python 3.4 was built using clang (not gcc, which the buildbots use)

Removing Python 3.4 from the system and rebuilding makes the issue go away.

The question is, what is ./python from the buildbot build directory doing using, loading or otherwise interacting with the python installation on the system in the first place? Is a lack of isolation the root cause?
