[New-bugs-announce] [issue22898] segfault during shutdown attempting to log ResourceWarning

[A. Jesse Jiryu Davis]

New submission from A. Jesse Jiryu Davis:

Running a unittest suite for Motor, my MongoDB driver which uses PyMongo, greenlet, and Tornado. The suite commonly segfaults during interpreter shutdown. I've reproduced this crash with Python 3.3.5, 3.4.1, and 3.4.2. Python 2.6 and 2.7 do *not* crash. The Python interpreters are all built like:

./configure --prefix=/mnt/jenkins/languages/python/rX.Y.Z --enable-shared && make && make install

This is Amazon Linux AMI release 2014.09.

The unittest suite's final output is:

----------------------------------------------------------------------
Ran 15 tests in 265.947s

OK
Segmentation fault (core dumped)

Backtrace from a Python 3.4.2 coredump attached.
