That link doesn't crash for me, for what it is worth, on what looks like the 5-19 Nightly.
Instacrash here when opening this URL,
try scrolling maybe.

Could you try using mozregression to get a regression range for this?
This is the top nightly crash in the most recent day. Looks like it spiked on 20150519030202. The 0520 volume is low right now, but maybe that's just because that build is still very new.
mccr8 - were you testing with Windows? I don't see crashes from other OSes.
No crash for me.  Running Windows 8.1 x64 and the latest inbound x64-PGO.  e10s on.

I tried both OSX and Windows 7 without a crash.

Bug 1162199 is in that range.  I don't have any reason to suspect it specifically, aside from that it is a large change.
Terrence also landed bug 1163810 and bug 1163790, which are more explicitly GC-related changes.
This could also be a dupe of bug 1166542, which has a similar regression range, involves a GC-ish crash, and has a test case on another Google web site, Maps.

Sure looks like it. Alice could you try the revision from that bug?

I'm going to say yes, based on crash-stats.

Given that fix for bug 1166277 landed in moz-central on 05/20 and since that day there are no new crash reports on FF41, I am setting the status flag as "Fixed". I also do not think we need to track this for FF41. Please re-nominate if you disagree.
