In Gentoo, I compile my system with -O0

When I compile Apache Serf, python 3.7.8 crashes. When I compile python 3.7 with -O2, python don't crash when compiling Serf.

It's the first time that -O0 causes program crash.

I run test suite, I don't have any problem.

Please find enclosed the backtrace.

I can reproduce every time so if you want me to do some tests, I can do it.

I already report it to Gentoo ( but it seems it's not related to them.

I still have the problem with python 3.7.9 but not with python 3.8.6.

Since I migrated my system to python 3.8, it's not a problem anymore. I still have python 3.7 installed so if you want, I still can do some tests.
