Red Hat Product Errata RHEA-2004:267 normal SHIPPED_LIVE Updated bison package fixes crash 2004-09-01 04:00:00 UTC

Description Göran Uddeborg 2004-02-25 15:43:03 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030922

Description of problem:
Running bison on this three line input file


results in a segmentation violation.

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

How reproducible:

Steps to Reproduce:
1.bison ah.y    

Actual Results:  bash-2.05b$ bison ah.y
Segmentation fault

Expected Results:  A correct (if pretty uninteresting) ah.c parser.

Additional info:

This does not happen on i386.  It happens on x86_64.

I'm aware omitting the final semicolon from rules is considered
obsolecent.  For a while bison warned about it, but that seems to be
gone again.  In any case, it should not crash.

Comment 1 Roland McGrath 2004-06-25 08:48:31 UTC
This is fixed by upgrading to version 1.875c, which will be in the
next erratum.
