Testing a trunk build, rev 15773a9 built on Friday May 29th, this
assertion failure is reproducible:

{{{

}}}

From the panic messages and varnishlogs we've seen so far, it seems to
have been an ESI-included 204 No content response in every case.

I'll attach a full stack trace. We can't post the panic message publicly,
but I can send one separately if needed.
