Topic

An updated byacc package that fixes one bug is now
available for Red Hat Enterprise Linux 6.

Description

Berkeley Yacc (byacc) is a public domain look-ahead left-to-right (LALR)
parser generator used by many programs during their build process.

This updated byacc package includes a fix for the following bug:

  • Byacc's maximum stack depth was reduced from 10000 to 500 between byacc

releases. If deep enough else-if structures were present in source code
being compiled with byacc, this could lead to out-of-memory conditions,
resulting in YACC Stack Overflow and build failure. This updated release
restores the maximum stack depth to its original value, 10000. Note: the
underlying LR algorithm still imposes a hard limit on the number of
parsable else-if statements. Restoring the maximum stack depth to its
original value means source code with deep else-if structures that
previously compiled against byacc will again do so. (BZ#743343)

All byacc users should upgrade to this updated package, which fixes this bug.

Solution

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
