Description Jukka Salmi 2003-05-26 11:22:32 UTC

GNU Awk 3.1.2 has problems when parsing multiline records. see "Steps to
Reproduce" for details.

Reproducible: Always
Steps to Reproduce:
$ od -c data
0000000   a  \n  \n   b  \n  \n   c  \n
0000010
$ cat pr.awk
BEGIN { RS = "" }
{ printf("%d: %s\n", NR, $0) }
END { print NR }
$ cat data | awk -f pr.awk
1: a
2: b
2
Actual Results:  
the last record (#3, containing 'c') is not printed

Expected Results:  
record #3 should be printed...

i sent a bug report regarding this problem to bug-gawk@gnu.org. stepan kasal
sent me a patch which fixes the problem. it's available from
http://www.math.cas.cz/~kasal/gawk/gawk-3.1.2-rsnull2d.patch.gz

i'm not sure wether any of the core utilities depend on multiline records or
not, so i file this report with severity "major".

arnold robbins - the maintainer and developer of gnu awk - said (regarding the multiline records problem):

  "This bug is only in 3.1.2, it is a bug. For now, the solution is to move       
   back to 3.1.1.  I am working on 3.1.3 and hope to release it "soon",           
   which will fix the problem."

Az: think we should back down the stable version and wait for 3.1.3?

Comment 3 Jukka Salmi 2003-06-01 09:49:33 UTC

yes.

Comment 4 Brandon Low (RETIRED) gentoo-dev

marked unstable.  Will wait for 3.1.3 for a new stable gawk.

Comment 5 Jukka Salmi 2003-06-23 01:22:00 UTC

And now it's marked stable again, still containing the bug... ???

Apply patch or mask again ?  Maybe do a new revision of 3.1.1 afterwards ?

Comment 7 Jukka Salmi 2003-06-23 14:32:40 UTC

I'd mask it again, because of Arnold Robbins statement. But I'm not sure if no other packages depend on functionality added to Awk between 3.1.1 and 3.1.2...

Nope, latest revision 3.1.1 have filefuncs.so in.
