To the best of my knowledge, this build doesn't build or use libgobject anymore.

That said, I totally believe that there are plenty of real data races deep inside libgobject.

Labels: Fuzz-Blocker M-67 ReleaseBlock-Beta
This crash occurs very frequently on linux platform and is likely preventing the fuzzer ochang_domfuzzer from making much progress. Fixing this will allow more bugs to be found.

Marking this bug as a blocker for next Beta release.

If this is incorrect, please add ClusterFuzz-Wrong label and remove the ReleaseBlock-Beta label.

I wonder if this is distro-related.
Adding to the stability sheriff queue for now. I am not sure where to start, so cc-ing sadrul@ and thomasanderson@ who own/have committed to platform/x11.
M67 Beta promotion is coming VERY soon. Pls make sure to land the fix and request a merge into the release branch ASAP. Thank you.

global_menu_bar_registrar_x11.cc is the only thing left that uses glib's dbus API.  We really ought to switch it over to our own src/dbus which will fix this issue as a bonus.
