Building the same chromium revision (crrev.com/575778) locally with goma does not reproduce the problem.

Labels: clang
Building with locally-built clang rev 337326 does reproduce the failure. Marking this as a Clang problem.

Comment 3 by inglorion@chromium.org, Jul 18 

Clang rev 337190 (https://reviews.llvm.org/D49320) is the first that causes this to fail.
