Description Konrad J Hambrick 2011-10-04 06:50:59 EDT
Created attachment 526225 [details]
contains two files:  ProcessParms.awk and a parameter file

Description of problem:

Complex Scripts fail with YACC Stack Overflow.  These same scripts have been working on RHEL and as far back as RH 4.2.  Works on RHEL 4 and 5 and it works on gawk 3.1.7 compiled from source with GNU Bison instead of byacc

Version-Release number of selected component (if applicable):

gawk 3.1.7 ( gawk-3.1.7-6.el6.i686 )

How reproducible:  every time

Steps to Reproduce:
1. download the attachment
2. cd  into a temp working directory
3. tar -zxvf gawk-yacc-stack-overflow-B11004.tgz
4. /bin/gawk -f ProcessParms.awk ppdf-rsync-proc-iplinput.26923
Actual results:

   gawk: ProcessParms.awk:202: YarCmpTab = $2 ""
   gawk: ProcessParms.awk:202: ^ yacc stack overflow

Expected results:

   silent return from ProcessParms.awk

Additional info:

tar -ztvf gawk-yacc-stack-overflow-B11004.tgz

Comment 2 RHEL Product and Program Management 2011-10-04 07:09:13 EDT
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated
in the current release, Red Hat is unfortunately unable to
address this request at this time. Red Hat invites you to
ask your support representative to propose this request, if
appropriate and relevant, in the next release of Red Hat
Enterprise Linux. If you would like it considered as an
exception in the current release, please ask your support
Comment 3 Vojtech Vitek 2011-10-04 20:38:38 EDT
The bug is in byacc component (byacc-1.9.20070509-6.1.el6 build), so I've opened bug 743343. After it's resolution I can fix gawk by rebuilding the package..
