--- Comment #7 from Yusuke Suzuki <ysuzuki at apple.com> ---
It is saying,

1. If the world is normal.
2. If m_wrapper is gone.
3. If m_jsFunction is not gone.

Then, the assertion hits. But this is wrong. We have no guarantee that m_jsFunction is gone when m_wrapper is gone. We have conservative GC. We have generational GC. Everything makes it possible that m_jsFunction is live while m_wrapper is gone.
I'll remove this assertion.
