# 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"}'

#
