CPython needs to be regularly built and vetted for C undefined behavior.

CFLAGS=-fsanitize=undefined LDFLAGS=-fsanitize=undefined CC=clang LD=clang ./configure

is all it takes to start with.

if you do this today, test_ctypes will knock your socks off with errors.  We should detect this type of build and intentionally skip its tests on ubsan, tracking that with another yet to be filed issue.

I'll look into having Google run one.
