Confirmed, with the JIT-less build crashing in Node::dispatchEvent, the event argument in that method is actually pointing to the same address as HTMLNames::audioTag. Odd.

Program received signal SIGSEGV, Segmentation fault.
0x00007ffff4856db0 in WebCore::Node::dispatchEvent (this=0x9e1630, event=...) at ../Source/WebCore/dom/Node.cpp:2112

2115        if (event->isTouchEvent())
2116            return dispatchTouchEvent(adoptRef(toTouchEvent(event.leakRef())));

this = 0x9e1630
event = {m_ptr = 0x6bdcc0}
(gdb) p HTMLNames::audioTag
$3 = {m_impl = 0x6bdcc0}
