Or a regression. Unsure which

somehow I mixed up two crashes/signatures. correct sig is arena_dalloc_small | arena_dalloc | je_free | nsFolderCompactState::`vector deleting destructor''(unsigned int) I didn't do an exhaustive check, but looks like version 12 crashes have nsSaveMsgListener::Release. And then version 14 has nsMsgComposeSendListener::Release bp-b34a3f6a-942c-4280-bf79-96a952120805 0 mozglue.dll arena_dalloc_small memory/jemalloc/jemalloc.c:4486 1 mozglue.dll arena_dalloc memory/jemalloc/jemalloc.c:4614 2 mozglue.dll je_free memory/jemalloc/jemalloc.c:6541 3 xul.dll nsFolderCompactState::`vector deleting destructor' 4 xul.dll nsMsgComposeSendListener::Release mailnews/base/src/nsMsgFolderCompactor.cpp:73 5 xul.dll nsRefPtr<nsCanvasPatternAzure>::~nsRefPtr<nsCanvasPatternAzure> objdir-tb/mozilla/xpcom/build/nsCOMPtr.cpp:81 6 xul.dll nsMsgProtocol::~nsMsgProtocol mailnews/base/util/nsMsgProtocol.cpp:119 7 xul.dll nsMailboxProtocol::`vector deleting destructor' 8 xul.dll nsNotifyAddrListener::Release js/xpconnect/src/XPCComponents.cpp:2227 9 xul.dll nsRefPtr<nsXULDocument>::assign_assuming_AddRef objdir-tb/mozilla/dist/include/nsAutoPtr.h:896 10 xul.dll nsCOMPtr_base::assign_with_AddRef objdir-tb/mozilla/xpcom/build/nsCOMPtr.cpp:89 ludo, can you check if code is roughly the same?

(In reply to Wayne Mery (:wsmwk) from comment #1) > ludo, can you check if code is roughly the same? Looks identical.

Thanks ludo. This is probably the continuation of bug 673904

This crash signature appears to be gone in TB17.0.2
