3.1.0 core dumps. Fiddling with OFMT?

[David Jones]

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"}'

Cheers,
