QA can anyone reproduce this or get STR?

I'm not even sure where to begin. There are no comments in the crash reports and I don't see any correlations.

Hey Gavin, we don't have any good leads for QA to pick up on, but we do know that this topcrash was fixed on or soon after 14.0a1/20120418. Any suspect (or rather beneficial) changes in that build?
Comment 4 User image :Gavin Sharp [email:] 2012-05-09 17:26:45 PDT
gcp backed out bug 673470 on April 20th. That backout also made it to beta (bug 673470 comment 100).
Comment 5 User image Gian-Carlo Pascutto [:gcp] 2012-05-09 17:45:26 PDT
I backed the relevant code out of beta the 1st of May, so betas built after that date should be unaffected.

The sanity/corruption check on line 361 should be done before line 275 too.

There are no crashes in versions above 13.0b1.
Comment 7 User image Gian-Carlo Pascutto [:gcp] 2012-08-15 00:17:19 PDT
The code that was causing this is landing again in bug 673470, but has a fix applied:
