--- Comment #32 from Marc Glisse <glisse at gcc dot gnu.org> --- (In reply to Misty De Meo from comment #31) > For what it's worth, Apple's response was: "We analyzed the issue and > determined the problem to be a latent bug in gcc’s build system that is > revealed by changes in macOS High Sierra. The FSF will need up issue a fix > in gcc." Thanks for forwarding. Their response is oh so precise and helpful... "bug on your side, washing my hands". I can't complain since I basically did the same thing in my previous comment, but if they really did analyze the issue, one might expect that they would share what the bug actually is :-(
