Sage 9.6 crash

[Luis Finotti]

I've recently started having Sage (up to date) crash.

The log is here: https://web.math.utk.edu/~finotti/tmp/Sage_crash_report.txt

The system is running Linux Debian Sid (up to date).  (I can provide more details if necessary.)

My guess is that it might be because I've installed/updated some packages with pip.  Like jupyterlab, black, pandas, jupyterlab_code_formatter.  I also updated pip.

Here is the result of pip list from a Sage shell: https://web.math.utk.edu/~finotti/tmp/sage_pip.txt

This has also happened in a different system.  I could reinstall from scratch.  On a third system, in which I am pretty sure I also installed/updated the packages with pip (also running Debian Sid), I did not have this problem.

Any suggestions?  Is installing packages with pip a bad idea?

From the crash report:

ImportError: libflint-2.8.5.so: cannot open shared object file: No such file or directory

Likely, a system update (apt-get upgrade) removed this version of the shared library.

Rebuild Sage from scratch.

Thanks!  Indeed in an update libflint-2.8.5 was updated to 2.9.0. 

I've successfully rebuilt and it seems to be running fine.
