Stack-overflow in SkRegion::op

Project Member Reported by ClusterFuzz, Mar 23 2016

Issue description

Owner: wangxianzhu@chromium.org
Status: Assigned (was: Available)
Suspected CL: https://chromium.googlesource.com/chromium/src/+/468ca56ab508342df50c7ee16ac4f4e767a1614b
wangxianzhu@ could you please look into this. Thanks
Status: WontFix (was: Assigned)
My CL is unrelated because it's about paint invalidation while the crash is during layout.

The test case is not minimized so unable to analyze it. It seems that it tries to create a very deep DOM for which stack overflow is unavoidable.
