This is a serious security regression. If you are not able to fix this quickly, please revert the change that introduced it. If this doesn't affect a release branch, or has not been properly classified for severity, please update the Security_Impact or Security_Severity labels, and remove the ReleaseBlock label. To disable this altogether, apply ReleaseBlock-NA. For more details visit https://www.chromium.org/issue-tracking/autotriage - Your friendly Sheriffbot

The listed regression range includes two HTML files for a test, and rev'ing the clang version number. From the stack, this looks like one of those unreproducible flakes in GTK code.

Abhishek, is there anything that we can do with this besides close it?

Hmm, issue 817742 has the same regression range, and is marked as reproducible. I guess that these are somehow a consequence of the Clang roll?

ochang@: Is this the same as issue 817742? It has a different stack but gives the same regression range, and is also a use-of-initialized-value in GTK.

Issue 818141 is a similar case: GTK, different stack, same range, reproducible.
