Hmm, can't repro this one locally. Maybe ASAN runs with a smaller stack?

Comment 3 by senorblanco@chromium.org, Jun 12 2017 

Update: I can repro this with an ASAN build (downloaded from https://commondatastorage.googleapis.com/chromium-browser-asan/index.html?prefix=linux-release/), just not with a non-ASAN build.

Comment 4 by senorblanco@chromium.org, Jun 12 2017 

Update: local ASAN build crashes, local non-ASAN build doesn't crash (both at same rev).

Since this only repros in ASAN and not in Chrome, I'm lowering priority. Feel free to update if you disagree.

Status: WontFix (was: Assigned)
ClusterFuzz testcase 5429675731189760 is flaky and no longer crashes, so closing issue.

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