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

$ 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

Actual Results:  
the last record (#3, containing 'c') is not printed

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 From Jukka Salmi 2003-06-01 09:49:33 0000 ------- 
yes.

------- Comment #4 From Brandon Low (RETIRED) 2003-06-08 15:53:42 0000 ------- 
marked unstable.  Will wait for 3.1.3 for a new stable gawk.

------- Comment #5 From Jukka Salmi 2003-06-23 01:22:00 0000 ------- 
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 From Jukka Salmi 2003-06-23 14:32:40 0000 ------- 
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.
