------------------------------

             Summary: background_fetch.so segfaults with no arguments as a global plugin.
                 Key: TS-4252
                 URL: https://issues.apache.org/jira/browse/TS-4252
             Project: Traffic Server
          Issue Type: Bug
          Components: Plugins
            Reporter: Peter Chou


In "plugin.config" if we just do background_fetch.so with no arguments we get a segmentation fault with messages saying invalid option with argument text from previous lines in the configuration file. If I just add a garbage argument like "background_fetch.so bleah" there is no fault.

I noticed that this plugin initialized optind to 1 before calling getopt_long while others such as tcpinfo set it to 0. Setting it to 0 also prevents the fault. Is this the correct fix?
