Comment 2

[Boris Zbarsky [:bzbarsky]]

Line 729 looks like this (no surprise):

726 static void
727 ClassSelector_ClearEntry(PLDHashTable *table, PLDHashEntryHdr *hdr)
728 {
729   (static_cast<ClassSelectorEntry*>(hdr))->~ClassSelectorEntry();
730 }

I wonder what gives here....

THere's currently nothing in crash stats per https://crash-stats.mozilla.com/report/list?signature=ClassSelector_ClearEntry#tab-reports

nsCSSRuleProcessor.cpp no longer exist so there's no point in
tracking this signature anymore.  Please file new bugs as appropriate.
