Testcase #2 indeed does reproduce more reliably.

Bug 828312 looks like the culprit. On builds from around the time of the initial regression, the crash is on a line touched by part 2 specifically.

While fuzzing Firefox 63.0.3 on Windows 10, I encountered this crash. I verified that it still happens in Firefox Nightly (Build ID 20181210095504):

Could you file a different bug for that please? A minimized test-case would be ideal, but not required.
