I've hit this assertion failure at least twice now using the inspector when switching to another resource in the sidebar.

Comment 1 2008-01-18 03:57:43 PST
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?

I've been hitting this more and more lately, especially since the improved inspector console landed. Always happens when I'm clicking a url in a console message.
