This is the "Temporary instrumentation" for bug 625646.

Comment 3 by dgn@chromium.org, Jul 26 2017

Owner: thomasanderson@chromium.org
This check can be hit if something goes wrong in random places in Chrome, unrelated to the browser_process_impl changes.

The report logs mention a NOTREACHED being hit:

Not implemented reached in virtual void views::DesktopWindowTreeHostX11::InitModalType(ui::ModalType)

https://cs.chromium.org/chromium/src/ui/views/widget/desktop_aura/desktop_window_tree_host_x11.cc?type=cs&q=desktop_window_tree_host_x11.cc:1097&sq=package:chromium&l=1097

Tom can you please have a look? (selected you seeing multiple recent changes to the file..)

Status: WontFix (was: Available)
ClusterFuzz testcase 4972965577097216 is flaky and no longer reproduces, so closing issue.

If this is incorrect, please add ClusterFuzz-Wrong label and re-open the issue.
