Hi,
I've been trying for a while to get a patchbot up and running in the
Docker container for Sage, and keep running into a problem that I seem
to only be getting in a container, with the two (likely related) test
failures in the log I pasted below.
It's strange because if I fire up a fresh container and run just
sage -t /opt/sage/src/sage/tests/cmdline.py
it passes. But when I run the full test suite it fails. In fact,
even when running
sage -t -a --long || sage -t -a --failed
these two tests failed both times.
Any ideas what could be causing random segfaults in Singular?
Thanks,
Erik
