Hi,
I would like to report a crash:
Operating System: Debian Linux Testing
carlos@arroway:~$ uname -a
Linux arroway 4.19.0-5-amd64 #1 SMP Debian 4.19.37-6 (2019-07-18) x86_64
GNU/Linux
SageMath was installed from Debian Repositories:
apt-get install sagemath
SageMath crashes right after intitialize:
carlos@arroway:~$ sage
┌────────────────────────────────────────────────────────────────────┐
│ SageMath version 8.6, Release Date: 2019-01-15 │

**********************************************************************
Oops, Sage crashed. We do our best to make it stable, but...
Best Regards,
Carlos
