Android Nexus5X Perf failing *.tough_pinch_zoom_cases

Project Member Reported by charliea@chromium.org, Apr 8 2016

Issue description

Revision range first seen: 385938 : 385950
Link to failing step log: https://build.chromium.org/p/chromium.perf/builders/Android%20Nexus5X%20Perf%20%282%29/builds/258/steps/smoothness.tough_pinch_zoom_cases/logs/stdio

Looking in the revision range, it looks like https://chromium.googlesource.com/chromium/src/+/21d8ab14ef1f9ba1add62b264141bacc9fab0f90 may be responsible.

boliu@, could your change have caused failures for the tough pinch zoom case tests?

(Assigning to rschoen@, current perf sheriff.)

No. My CL is zoomBy/zoomIn/zoomOut APIs on webview. It doesn't change anything about pinch zoom, and doesn't change anything in chrome either.

Failure is a crash in the renderer it looks like, but it never got symbolized correctly for whatever reason:

Comment 2 by boliu@chromium.org, Apr 8 2016

Actually, *nothing* from libchrome.so got symbolized correctly. Might have to do with the .so being mapped directly to memory from the apk. Dunno..
Summary: Android Nexus5X Perf failing *.tough_pinch_zoom_cases (was: Android Nexus5X Perf (2) failing smoothness.tough_pinch_zoom_cases)
Any updates on this? This is still failing. Looking at Nexus 5x Perf (2) builder page (https://build.chromium.org/p/chromium.perf/builders/Android%20Nexus5X%20Perf%20%282%29?numbuilds=200) this looks like it's been failing since around Mar 31?
