It was built from sources because I needed SSL's server name
indication (SNI) of Python 3.x. The version installed in
/usr/local/bin was a standard build, and lacks any instrumentation
like Asan and UBsan.

Here are the two results:
$ /usr/local/bin/python /usr/local/bin/asan_symbolize.py
File "/usr/local/bin/asan_symbolize.py", line 69
print ' '.join(cmd)
^
SyntaxError: invalid syntax
$ /usr/bin/python /usr/local/bin/asan_symbolize.py
^C
So it looks like something is broken with my build of 3.3.

Ah, right... I forgot about that. Thanks.
Thanks for the help. (Would you know what I should do next, before I
head over to the Stack Overflow).
