I'm having the same assertion, in a different place. This is due to
HashMap/HashTable not allowing key values 0 or -1 for integer->* maps. They are
reserved as the "empty" and "deleted" bin values.

In my case, NPN_GetIntIdentifier uses HashMap<int32, NPIdentifier> to associate
integer keys with unique NPIdentifiers (actually PrivateIdentifier*). When a
plugin asks for an NPIdentifier associated with 0 or -1, it will assert. I'm
currently working around this by remapping the incoming int32 values to uint64
and setting bit 32, thus avoiding values 0 or -1.

It's a silly workaround. Can we make HashMap stop using special values for
integer keys?
