It's a bit interesting only because it is so odd.

Can you double-check that your gcc-7.3 setup is actually building the same tree?

Yeah, I know that's a slightly strange thing to ask, but your build
log really looks very odd. There should be nothing in that error that
is in any way compiler version specific.

Sure, we may have some header that checks the compiler version and
does something different based on that, and I guess that could be
going on. Except I don't even find anything remotely like that
anywhere. I do find some compiler version tests, but most ofd them
would trigger for all those compiler versions

Or is there perhaps some other configuration difference?
