Automatically assigning owner based on suspected regression changelist https://chromium.googlesource.com/chromium/src/+/ca2623e17b5c45400485a2ceb08545baa9f09c4f (Optimize ClipRects in the PrePaintTreeWalk.).

Not clear that we need to support 3000 level deep nested elements. I'd be happy WontFix on this.

ClusterFuzz testcase 6741825858830336 is still reproducing on tip-of-tree build (trunk).

If this testcase was not reproducible locally or unworkable, ignore this notification and we will file another bug soon with hopefully a better and workable testcase.

Otherwise, if this is not intended to be fixed (e.g. this is an intentional crash), please add ClusterFuzz-Ignore label to prevent future bug filing with similar crash stacktrace.

This is a common crash in real world (top blink crash by far), judging from Opera crash reports. Some 370 nested calls to blink::PrePaintTreeWalk::Walk(blink::LayoutObject const&, blink::PrePaintTreeWalkContext const&) ending with a crash. 

Crash Reason	EXCEPTION_STACK_OVERFLOW

Something needs to not be recursive or use much less stack if it is recursive. Example of a common url triggering it: https://clients5.google.com/pagead/drt/dn/

Updating the status to 'Assigned'.

A note, what I said above was for Chromium 61. I can't see a similar crash in top 10 for 62 and 63 in Opera so maybe it used to be worse than it is now, and now is ok?

Nevertheless I WontFixed this bug as this is not a security issue.

This is tracked in bug 781301 so closing this one again.

ClusterFuzz has detected this issue as fixed in range 514498:517698.
