wiil look at this, thanks.

[maehne (Torsten Maehne)]

I am observing the build failure of webkit2-gtk @2.26.0_0 on macOS High Sierra 10.13.6 as well.

[kencu (Ken)]

it built on the 10.13 buildbot <​https://build.macports.org/builders/ports-10.13_x86_64-builder/builds/71173>.and for me...

[pmetzger (Perry E. Metzger)]

It might have to do with subtleties of local configuration. In any case, this is sort of a critical problem.

[pmetzger (Perry E. Metzger)]

FYI, this is a serious problem. We really need to get it resolved. webkit2-gtk is an essential package.

[kencu (Ken)]

yuk. maybe just that same stack protector thing?
