Illegal Instruction (core dumped) on CentOS 7


I am running on an HPC cluster which contains 4 different Intel CPU generations, the oldest of which is Nehalem (which has SSE4.2).  Whenever I run `help("modules")` in either the python2 or python3 distribution on our two older architectures (family 6, model 44 and 45), I get an illegal instruction exception and python crashes.  It seems to be whenever it is doing the deprecation check on matplotlib. It runs fine on all of our newer (AVX and up, through Haswell) machines. attached is a screenshot of the error occurring and the cpuinfo output for each architecture.


OS is CentOS 7, 3.10.0-229.el7.x86_64 #1 SMP Fri Mar 6 11:36:42 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Hi Michael, thanks for the extended info on the issue you are running into.  I've let the engineering team know about it–they are looking into the issue now.

Hi Michael,

I'm trying to reproduce issue you reported. Unfortunately it seems that matplotlib isn't enough in my configurations.

Could you send what 'help("modules")' prints when it finishes successfully. 

And if you installed Python with conda's help then send us 'conda list' output too, please.
