On CentOS7 build properly

Try with latest master and if still problems, reopen.

[miconda]

Hmm, it seems to be specific to old distros (likely old versions of flex and bison), on ubuntu 20.04 where I could reproduce --atexit issues, works fine. I need to get access to a centos 7 to see what flex/bison generates.

[miconda]

Try again with latest master, seems to be ok on centos 7.

@miconda, are you use docker on your dev PC?
