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?
