Comment 1

[Olli Pettay [:smaug][[e-mail]]]

mccr8, you added the assertion. Does this ring any bells?

Comment 2

[Andrew McCreight [:mccr8]]

I don't really remember this code, but it looks like we'll hit this assertion if RemoteObjectProxyBase::GetOrCreateProxyObject() fails to create anything. My guess would be that this is a sign of an OOM.

Comment 3

[Chris Peterson [:cpeterson]]

This is an unrecoverable JS API failure. Comment 0's crash report has a JSOutOfMemory: Reported annotation.
