Comment (by fgsch):

 Thanks. Is this something you can reproduce or crashes randomly after some
 time?

 If so if you could follow the steps at https://www.varnish-
 cache.org/trac/wiki/DebuggingVarnish to get a useful coredump it'd be
 appreciated.

 Also trying to pinpoint which regex and/or request is causing the crash
 would be great.
