Silent crash when running the Celery test suite

[thedrow]

The following test silently crashes Pyston without any further information.

We should investigate.

thanks for the bug report!

Could you please help me with reproducing the issue.
It tried the following:

virtualenv -p /usr/bin/pyston celeryenv
cd celeryenv
. bin/activate
pip install pytest
git clone https://github.com/celery/celery.git
cd celery
pip install -U -r requirements/test.txt
pip install -U -r requirements/default.txt
pip install -e .[mongodb]
pytest t/unit/backends/test_mongodb.py
86 passed in 0.28s

Which seemed to work

I reproduced it on a Docker container.
I'll try it again.
