[ltt-dev] [UST PATCH] Fix bug in test_functions.sh

[nils@as68123.uab.ericsson.se (Nils Carlson)]

Getting weirder and weirder...

This test fails on two of my machines:

#!/bin/bash

function optind_test() {

      while getopts "a:b:c:" flag; do
         case $flag in
             a) echo $OPTARG;;
             b) echo $OPTARG;;
             c) echo $OPTARG;;
         esac
      done
}

optind_test -a hi  -b thats nice
optind_test -c whats
echo ------


Adding a "local OPTIND=" after the function line makes everything work, 
but it shouldn't fail. According to POSIX OPTIND should be function local 
already.
