I'm porting WebKit to a custom platform, and have been running into
problems with LEAKED node references for DOMs which include SCRIPT
elements. It seems the problem is that the BlockAllocator thread is not
exiting, because the BlockAllocator object is not being destructed. The
BlockAllocator object is a field of JSC::Heap, which is a field of
JSC::JSGlobalData.
JSGlobalData seems to be a Singleton created through
JSDOMWindowBase::commonJSGlobalData. It is ref-counted, but
JSDOMWindowBase::commonJSGlobalData returns a raw pointer. So it would
seem that the object returned from JSDOMWindowBase::commonJSGlobalData
has to be deallocated SOMEWHERE, either with a call to delete or a call
to ->deref(), but I've examined the GTK port and I can't see where it is
supposed to be allocated.
So, how is the JSGlobalData Singleton supposed to be deallocated?
