Hello,
I need help figuring out what's going on when I am preparing Sage for
SageMathCell.
When the script is at
https://github.com/sagemath/sagecell/blob/master/contrib/vm/container_manager.py#L445
trying to pipe some commands into a freshly compiled Sage it crashes. The
crash report is attached and the problem seems to be with a wrong or absent
terminal (given that it is done by a script in screen).
After the build there is "Sage starts OK" message and if I try to connect
via interactive terminal and execute commands by hand everything is fine.
Exactly the same setup was also going without crashes for 7.3, so it is
some recent change/upgrade.
Thank you!
Andrey
