Description

[Marcia Knous [:marcia]]

This bug is for crash report bp-e522eb14-6020-4f93-80b9-e6f510190710.

Seen while looking at Fennec 68 release crashes. This regression may have been in 67 cycle, but is much more prominent in early 68 crashes: https://bit.ly/2YHdCmW/. APIs range from 16-28 and are spread across a wide variety of devices.

Comments are not particularly useful.

Some of the code was touched in Bug 1551183 during the 68 cycle.

Nhi - Can you take a look when you get a chance to see if this is in the correct component? Thanks!

The cause is IMO the same as in bug 1550815, it just crashes at different place.
