So I've upgraded to gcc-7.1.0 because of #627414, and now I get:

[Comment 1 Ostashevskyi Viktor 2017-08-15 07:49:40 UTC]

Adding

cflags += [ "-fpermissive" ]

to third_party/WebKit/Source/BUILD.gn can be considered as a workaround.

Upstream patch here https://chromium-review.googlesource.com/c/616563

[Comment 3 Konstantin (elxa) 2017-08-21 18:21:25 UTC]

The patch worked for me, after the build failed I did
patch -p1 < patch.diff
ebuild <path to chromium-61.0.3163.39 ebuild> merge
installation completed without errors

Duping gcc-7 issues to one bug.
