Created attachment 599308 [details, diff] mozbug-1602358-be-cbindgen-support.patch W4M: patch for "too new cbindgen vs. too old firefox" (https://bugzilla.mozilla.org/show_bug.cgi?id=1602358) cpp template nuance/snafu. designed for /etc/portage/patches; may need massaging elsewhere. aside: Without having read clang's far, far less confusing error message, I might never have guessed this patch had anything to do with this problem... Sometimes I wonder if g++ has decided humans are an obscure legacy platform not worth supporting; I suppose our primitive "idea"-based IR impedes its optimizer :D
Works fine with the patch. Thank you.
Just to update that this bug should (now) be fixed by commit https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=7c8c8537773d7a63d54a253dcd21455dbbe48d43 I'm assuming it got fixed before this bug entry was noticed.

Thanks for pointing it out, guessing he just forgot to close it.
