    66  # Like my other bug, this is a regression from 3.1.0 and I've reproduced
    67  # this problem with 3.1.2d.

    72  # | Version: 1:3.1.2-2
    73  # | Severity: normal
    74  # | Tags: sid
    75  # | 
    76  # | After upgrading gawk from woody to sid, I found one of my scripts not
    77  # | working. I explored this a little and found minimal script to reproduce
    78  # | the problem.
    79  # | 
    80  # | File bug.awk is the following:
    81  # | 
    82  BEGIN  {
    83    WI_total = 0
    84  }
    85  {
    86    WI_total++
    87    {
    88      split (  $1, sws, "_" )
    89      a = sws[1]
    90    }
    91    print(sws[1])
    92    print(a)
    93  }
    94  # | 
    95  # | The second print should output the same what first print poutputs, but
    96  # | with gawk 3.1.2-2 it outputs nothing:
    97  # | > echo a_b | gawk -f bug.awk
    98  # | a
    99  # | 
   100  # | >
   101  # | 
   102  # | With gawk from stable I get what expexted:
   103  # | > echo a_b | gawk -f bug.awk
   104  # | a
   105  # | a
   106  # | >
   107  # | 
   108  # | If I remove "WI_total++" line, bug disapperas
