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? Linus
