MOZ_CRASH Reason (Sanitized) BUG: Unable to find glyph key cache!

Lee, do you have any suggestions?

Flags: needinfo?(lsalzman)

No idea offhand. Hard to diagnose without a testcase.

Jamie, the spike in the reports looks somewhat suspiciously timed to your text run bounds changes maybe?

Flags: needinfo?(jnicol)
Blocks: wr-80
Severity: -- → S3
Priority: -- → P3

I don't think that could have caused this: it didn't change anything outside of the callback which is called by fetch_gylphs() (after the point of the crash)

Flags: needinfo?(jnicol)
