# Subject: 3.1.0 core dumps.  Fiddling with OFMT?
# Date: Wed, 13 Jun 2001 14:45:54 +0000
# From: David Jones <djones@zoonami.com>
# Status: R
# 
# The following program causes gawk to dump core:
# 
# jot 10|./gawk '{OFMT="%."NR"f";print NR}'
# 
# 'jot 10', if you didn't know, produces the numbers 1 to 10 each on its
# own line (ie it's like awk 'BEGIN{for(i=1;i<=10;++i)print i}')
# 
# Here's an example run:
# 
# -- run being
# 1
# 2
# 3
# 4
# gawk: cmd. line:1: (FILENAME=- FNR=5) fatal error: internal error
# Abort trap - core dumped
# -- run end
# 
# Ah.  print NR appears to be not interesting.  The following program also
# has the same problem:
# 
# jot 10|./gawk '{OFMT="%."NR"f"}'
#
