Assert error in vfp_esi_bytes_gg()

Hi there,

I'm having the same issue described above regarding Vanish dying with the
error: Panic message: Assert error in vfp_esi_bytes_gg(), cache_esi_fetch.c
line 273:#012  Condition(i >= VGZ_OK) not true.

In my case, it happens only when a certain url pattern is met. This pattern
should normally resolve with a 404, but instead the server responds
with an Error
324 (net::ERR_EMPTY_RESPONSE) and then Varnish dies, throwing the
aforementioned error. I'm using Varnish 3.0.2 with ESI. Has someone
experienced this before or have any tips on how to debug it?
