 Hi Andy,

 The implemented fix misses a protection: something like this

if lxb6041.cern.ch
  <do something>
fi

 triggers a segv, because after matching correctly the host it tries

 strcmp(val,"exec") with val = 0x0.

 Shouldn't the host matching conditional read something like this

// Check if we are one of the listed hosts
//
   if (!is1of(val, brk))
      {do {hostok = XrdNetDNS::isMatch(hname, val);
           val = Config.GetWord();
          } while(!hostok && val && !is1of(val, brk));
       if (hostok)
          { while(val && !is1of(val, brk)) val = Config.GetWord();
            // No more directives
            if (!val) return 1;
          } else return 0;
      }
