I am attaching a stripped build log file, the problem occurs with gcc-7 but not with gcc-8 or gcc-9

You have to set the component to WebKitGTK if you want devs to look at your bug. I'm working on a hack solution to this, but I couldn't find any way to solve this in a way that would be acceptable to upstream, so I think we just need to require GCC 8.

Created attachment 402384 [details] Patch This is not proposed for review because it's ridiculous. I couldn't find another way, though.

I suppose this is going to lost all the relevance soon in April but current agreement was to keep GCC7 as an valid compiler to build Webkit at least until the EOL of Ubuntu 18.04: (GCC 7 OR Clang 6) AND libstdc++ 7, the versions in Ubuntu 18.04, will be supported until April 2021 Ref: https://trac.webkit.org/wiki/WebKitGTK/GCCRequirement

FWIW, I just tried a build with GCC 7.5.0 and did not hit this issue. Could it be some GCC issue that is unpatched in the version distributed with Ubuntu?

You are right. I saw the build working fine in https://build-webkit.igalia.com/builders/GTK%20Linux%2064-bit%20Release%20Packaging%20Stable%20%28Ubuntu%2018.04%29?numbuilds=200. This bug originally comes from a issue in the Gentoo tracker ('WTF::ObjectIdentifier<WebCore::PageIdentifierType>::ObjectIdentifier()). I was be able to reproduce the error in Yocto (Rocko) as well using GCC7 (version 7.3). Could be that the case in Gentoo too? * https://gcc.gnu.org/bugzilla/buglist.cgi?bug_status=RESOLVED&resolution=FIXED&target_milestone=7.4 * https://gcc.gnu.org/bugzilla/buglist.cgi?bug_status=RESOLVED&resolution=FIXED&target_milestone=7.5

No. I looks like Gentoo is in GCC 7.5 nowadays: https://gitweb.gentoo.org/repo/gentoo.git/tree/sys-devel/gcc/gcc-7.5.0-r1.ebuild
