found via bughunter on https://twitter.com/hashtag/ViernesDePiropos?src=tren&lang=es
and reproduced after multiple tries to load this site.
Bughunter is reporting a lot of different stacks for this site like signatures like : JS::Heap<JSObject*>::~Heap<JSObject*> `vector destructor iterator' mozilla::dom::ProtoAndIfaceCache::~ProtoAndIfaceCache mozilla::dom::DestroyProtoAndIfaceCache mozilla::dom::DedicatedWorkerGlobalScopeBinding_workers::_finalize
however i was able to catch a crash (xul!AssertNotOnGrayList+0x00000138) in windgb from this site.

I'd guess that this is a dupe of that image-related memory corruption that Seth is working on.

I think that would be bug 1206836.

If so, bug 1206836 is fixed now, so we shouldn't be hitting this anymore. Should this be resolved?

I retested this and although some of the workers are still pending, this still crashes with multiple different stacks on OSX and Windows. One of the Windows crashes is rated high exploitable while another is rated low with buildid 20150923030230 from mozilla-central. I think the exploitability rating plus the variety of stacks makes me think of memory corruption though the opt-asan linux builds haven't shown any errors.
The low rated windows debug crash looked like JSObject::writeBarrierPost nsWrapperCache::ClearWrapper mozilla::dom::HTMLPreElementBinding::_finalize JSObject::finalize js::gc::Arena::finalize<JSObject>
while the high rated windows opt crash looked like `anonymous namespace'::PerformanceEntryComparator::LessThan mozilla::BinarySearchIf<nsTArray_Impl<nsRefPtr<mozilla::dom::PerformanceEntry>, nsTArrayInfallibleAllocator>, detail::ItemComparatorFirstElementGT<mozilla::dom::PerformanceEntry*&, `anonymous namespace'::PerformanceEntryComparator> > nsTArray_Impl<nsRefPtr<mozilla::dom::PerformanceEntry>, nsTArrayInfallibleAllocator>::InsertElementSorted<mozilla::dom::PerformanceEntry*&, `anonymous namespace'::PerformanceEntryComparator, nsTArrayInfallibleAllocator> PerformanceBase::InsertResourceEntry nsPerformance::AddEntry
The OSX crashes appear to be related to jpeg images or jemalloc.
I reproduced locally on osx 10.9.5:
bp-22d56942-e2d8-4996-ada3-c8d172150923 and
[@ PLDHashTable::Iterator::Iterator(PLDHashTable*) ]
bp-f2afbc78-542a-4671-807c-d83a42150923
[@ RemoveSkippableVisitor::Visit(nsPurpleBuffer&, nsPurpleBufferEntry*) ]

Well, that's unfortunate. Thanks for retesting, Bob. I guess there's some other issue that's trashing memory.

Bob, could you maybe bisect this to figure out what change set caused it? Assuming it is a regression.

(In reply to Bob Clary [:bc:] from comment #4)
> The OSX crashes appear to be related to jpeg images or jemalloc.
It's worth noting that the JPEG decoder is one of the few decoders that didn't change in 43. That doesn't mean it doesn't have bugs, but it does mean that at least it's unlikely that the recent set of image decoder changes are the cause.

I have repeatedly tried on Windows, Linux and OSX to reproduce this again but have failed. I even tried to scroll down the page to make sure I loaded the content which was originally displayed.
So, either the content has changed sufficiently that it no longer reproduces or I was wrong about reproducing it after bug 1206836 was fixed. We can WFM this for now. If I see something similar, I'll file a new bug.
