I am unable to compile WebKit rev 16f89907d5e9 after this rev 16f89907d5e9 landed, using the following command:

`./Tools/Scripts/build-jsc --jsc-only --debug --cmakeargs="-DCMAKE_C_COMPILER='/usr/bin/clang' -DCMAKE_CXX_COMPILER='/usr/bin/clang++'"`

$ clang --version

Michael, is bug 277383 a likely regressor?

[Gary Kwong [:gkw] [:nth10sd]]

The immediate parent, webkit rev 718f9c8cd131, seems to compile just fine.

The compile error on a x86_64 macOS seems to be:

Tested on WebKit rev 6f39c4886559.

Ping, any hope of fixing this compilation failure anytime soon?
