Hum. Are you aware that PGO with GCC is broken on such old and unsupported Ubuntu version?

My old note about that:

"PGO is broken on Ubuntu 14.04 LTS with GCC 4.8.4-2ubuntu1~14.04: Modules/socketmodule.c:7743:1: internal compiler error: in edge_badness, at ipa-inline.c:895"

https://pyperformance.readthedocs.io/usage.html#compile

See also https://bugs.python.org/issue31963

I suggest you to not use PGO compilation on old Ubuntu. Maybe upgrade to latest Ubuntu LTS?
