I already used "-Wall -Wextra" in my cmake file. I also followed
https://gcc.gnu.org/bugs/ and tried "-fno-strict-aliasing -fwrapv
-fno-aggressive-loop-optimizations" and "-fsanitize=undefined" respectively.
These three situations all generated the same error "/executor.h:23:3: internal
compiler error: Segmentation fault"

gcc (Ubuntu 20200418-1ubuntu1) 10.0.1 20200418 (experimental) 

is a quite old prerelease.  Please update and re-try.  We also need
preprocessed source as a reproducer.
