    29  # Subject: 3.1.0 core dumps.  Fiddling with OFMT?
    30  # Date: Wed, 13 Jun 2001 14:45:54 +0000
    31  # From: David Jones <djones@zoonami.com>
    32  # Status: R
    33  # 
    34  # The following program causes gawk to dump core:
    35  # 
    36  # jot 10|./gawk '{OFMT="%."NR"f";print NR}'
    37  # 
    38  # 'jot 10', if you didn't know, produces the numbers 1 to 10 each on its
    39  # own line (ie it's like awk 'BEGIN{for(i=1;i<=10;++i)print i}')
    40  # 
    41  # Here's an example run:
    42  # 
    43  # -- run being
    44  # 1
    45  # 2
    46  # 3
    47  # 4
    48  # gawk: cmd. line:1: (FILENAME=- FNR=5) fatal error: internal error
    49  # Abort trap - core dumped
    50  # -- run end
    51  # 
    52  # Ah.  print NR appears to be not interesting.  The following program also
    53  # has the same problem:
    54  # 
    55  # jot 10|./gawk '{OFMT="%."NR"f"}'
    56  # 
    57  # Cheers,
