fukino-san, could you route this to whomever is doing the work to move us over to using file system mojo, please?

Comment 2 by noel@chromium.org, Sep 13 

Another test where this error shows up frequently:

https://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=GalleryBrowserTest.CropImageOnDrive

See the gray CRASH-PASS boxes on ASAN runs.

GalleryBrowserTest is a general place I see these. +tapted as an FYI.

adithyas@ - can you take a look. These tests tend to be a good smoke test for File System API usage.

+niwa@ is modifying file_system mojom to fix ARC-related issues

I'll take a look at this, it's probably something to do with some mojo bindings not being destroyed in the right order.

Status: WontFix (was: Started)
These tests have stopped being flaky on the dashboard for a while (after I landed https://crrev.com/c/1258202 which wasn't targeting fixing this issue), and I can't reproduce any flakiness locally. Closing for now.

Comment 9 by noel@chromium.org, Oct 9 

Agree.  Examined the bots this AM, no more CRASH PASS flakes.  Thanks for fixing.
