This bug was filed from the Socorro interface and is report bp-15705731-6122-4c02-ac77-fa7250170808. ============================================================= Seen while looking at nightly crash stats - these crashes go back to when 56 was in nightly and started in 20170720030203: http://bit.ly/2vi6xLz Possible regression range based on Build ID: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=1b065ffd8a535a0ad4c39a912af18e948e6a42c1&tochange=0985725c848ec0cfc6f2f3c3a5aa3d71321e7620
Hiro-san, could it be a stylo regression from bug 1381431?
Priority: -- → P2
I don't think bug 1381431 caused the crashes. I guess this crash was caused by fusing style context (bug 1367904). Also it seems to me that this crash has been fixed in 20170808 nightly. I think Manish already fixed the crash. Keep ni to me, I will revisit the crash report after this weekend.
There are no more crash reports after build id 20170808114032. This crash is probably fixed, as Hiro noted. https://crash-stats.mozilla.com/signature/?product=Firefox&signature=mozilla%3A%3ADeclarationBlock%3A%3AAsGecko#reports
