What steps will reproduce the problem?
(1) Build official base_unittests with or without LTO enabled. Below are the flags for non-LTO build (faster to link):

$ gn gen out/off '--args=is_chrome_branded=false is_official_build=true is_debug=false is_cfi=false use_thin_lto=false allow_posix_link_time_opt=false use_lld=false use_goma=true' --check

(2) Run base_unittests and observe the failure:

$ ./out/off/base_unittests
...

This test was introduced just recently, in https://codereview.chromium.org/2606153003/
Reverting the CL failed because the patch won't apply anymore.
