Segfault in varnishncsa when exclude regex matches

[Jacques]

I'm trying to use varnish on rhel6.1.  I get a segfault within the
varnishncsa when I use -X and the regex matches a call.

For example,

varnishncsa -X loadbalancer works until the request /test?loadbalancer ping
occurs.
varnishncsa -X foobar works indefinitely (as there are no requests which
match foobar)


Any thoughts?

Thanks,
Jacques
