Comment (by lygie):

 Using just the regex defined in the constant causes the same issue
 {{{
 VRT_re_init(&VGC_re_53,
 "(?i)Android.*Nexus[\\s]+(7|10)|^.*Android.*Nexus(?:(?!Mobile).)*$");
 }}}

 I tried a clean varnish4 setup just adding
 {{{
 sub vcl_recv {
         if(req.http.User-Agent ~
 "(?i)Android.*Nexus[\s]+(7|10)|^.*Android.*Nexus(?:(?!Mobile).)*$") {
                 set req.http.User-Test = "123";
         }
 }
 }}}

 causing the same segfault
