I think the problem is related to gcc-7 while building with gcc-8 works
(In reply to Fabio Rossi from comment #2) > I think the problem is related to gcc-7 while building with gcc-8 works Can you try without -ggdb, and with gcc 9? Please attach at least the top of, and then the last 250-400 lines of the build.log.

If I compile with gcc-8 or gcc-9 it works, even with -ggdb.

If I compile with > gcc-8 or gcc-9 it works, even with -ggdb. I don't think GCC 7 is supported anymore upstream, just GCC 8 / GCC 9 / GCC 10: https://gcc.gnu.org/ So is there a reason you need GCC 7?
(In reply to Sam James (sec padawan) from comment #6) > https://gcc.gnu.org/ > > So is there a reason you need GCC 7? Because I have installed it on an old and slow computer and cannot rebuild everything for each release of gcc. Anyway gcc-7 is still available in portage so I expect to be usable, otherwise there should be a check in webkit-gtk ebuild informing the user of incompatible gcc versions
It would be good to know WHY it fails with gcc7. What feature it uses that it doesn't have, or if it's hitting some bug or what. You already have newer gcc, just switch to it for webkit-gtk build then meanwhile. webkit-gtk doesn't expose any C++ API to consumers (besides 5 symbols that aren't public API), it'll work fine for consumers using older C++ ABI (though I'm not sure that changed significantly between gcc7 and 8 either).
I have also reported the bug upstream https://bugs.webkit.org/show_bug.cgi?id=212590
