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

             Summary: Command line not being parsed correctly with getopt not from glibc
                 Key: ASTERISK-27773
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27773
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Core/General
    Affects Versions: 15.3.0, 15.0.0
         Environment: FreeBSD 11.1
            Reporter: Guido Falsi


Asterisk 15 intriduces a two step command line parsing with getopt(3). Before calling getopt for the second time optind = 0 is called to reset the parsing engine. This works with glibc getopt implementation since it forces optind = 1 when optind == 0 [1]. That's wrong with other implementations not forcing the value to 1.

FreeBSD's getopt when getting optind == 0 checks if argv[0] is an option and since that fails (except the unrealistic case when argv[0][0] == '-') and stops parsing the rest of the command line. [2]

I'm going to file patches on gerrit shortly.
