We tried centos linux release 7.8.2003 and gcc 7.4.0.
There is no resources to restore your scenario.
Hope we can discuss it in mattermost.

I was able to bypass it by commenting utils/make/Makefile.common L49
This was adding the compilation command with the -Weffc++ option. But unable to compile successfully. Got some linker errors laters.
