            Bug ID: 246174
           Summary: math/gmp-6.2.0 with option CPU_OPTS crashes on Atom
                    CPU
           Product: Ports & Packages
           Version: Latest
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: Individual Port(s)
          Assignee: ports-bugs at FreeBSD.org
          Reporter: Axel.Rau at Chaos1.DE

The option "Enable assembly optimizations for your CPU" causes the crash of
gmp-6.2.0 on an Intel(R) Atom(TM) CPU C2758. This does not happen on
gmp-6.1.2_1.

The crash happens in python3.7/site-packages/Crypto/Math/_IntegerGMP.py

We have tried to find the cause in related Python packages here:

https://github.com/Legrandin/pycryptodome/issues/394
https://github.com/rthalley/dnspython/issues/446

but had no luck.

Stacktrace and part of dmesg below.
