Predator and CL could not provide any possible suspects.

Using Code Search for the file, "HTMLSlotElement.cpp" suspecting the below Cl might have caused this issue

Suspect CL: https://chromium.googlesource.com/chromium/src/+/7c44da721a59e6aa0b9fdcddb314175cb1e0123f%5E%21/third_party/WebKit/Source/core/html/HTMLSlotElement.cpp

hayato@ -- Could you please check whether this is caused with respect to your change, if not please help us in assigning it to the right owner.

Thanks!

Rune, it looks WhiteSpaceAttacher might be related.
Could you have a chance to take a look?

WhitespaceAttacher happens to be pushed onto the stack when we run out of stack space for a very deep DOM tree.

Labels: Needs-Feedback
ClusterFuzz testcase 4689416204058624 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.
