----------------------+-----------------------------------------------------
 I am running Varnish trunk (up to date to commit 1975) in FreeBSD
 6.2-RELEASE/amd64, on Intel hardware.

 Soon after starting Varnish and loading a few pages, it dies:

 Sep 21 11:48:13 cache10 kernel: pid 48887 (varnishd), uid 0: exited on
 signal 6 (core dumped)

 On the console:

 {{{
 Child said (2, 48887): <<Assert error in VBE_UpdateHealth(),
 cache_backend.c line 319:
   Condition((vc) != NULL) not true.
   errno = 0 (Unknown error: 0)
 >>
 Cache child died pid=48887 status=0x86
 }}}

 My VCL:
