Segmentation Fault on GitLab CI, unittest in conda env

Hi,

I’m using GitLab.com service. I’ve got a strange segmentation fault when doing Python unittest in GitLab CI. Since there’s no further detailed log on why it happened, I can’t figure it out.

We’re trying to create a conda environment first, then do a usual Python unittest as python -m unittest discover. But the following logs showed at the end of this GitLab CI Job:

$ python -m unittest discover
/bin/bash: line 123:  2259 Segmentation fault      (core dumped) python -m unittest discover
ERROR: Job failed: exit code 1

I’ve tried to increase stack size by setting ulimit -s 100000, bit it didn’t work. Hope somebody can point out anything to try. Thanks.
