When running

/usr/bin/python /usr/bin/pip install --upgrade "pip < 10"

the interpreter crashed in stackdepth_walk. I've seen this crash multiple times, especially in our custom-compiled CPythons. Here it's 
reproduced with stock Ubuntu Xenial Python. It looks like it happens much more often on AMD Ryzens although it happens also on Intel CPUs.
The Ryzen is otherwise stable.

Sys details:

Python 2.7.12 (default, Nov 12 2018, 14:36:49) 
[GCC 5.4.0 20160609] on linux2

Package python-minimal 2.7.12-1~16.04 from Ubuntu Xenial
