RHBA-2012:0936 - valgrind bug fix and enhancement update


Synopsis

valgrind bug fix and enhancement update

Type/Severity

Bug Fix Advisory

Topic

Updated valgrind packages that fix one bug and add one enhancement are now available for Red Hat Enterprise Linux 6.

Description

The valgrind packages provide a programming utility for debugging memory, detecting memory leaks, and profiling.

This update fixes the following bug:

  • Prior to this update, the "memalign" and "posix_memalign" replacements could only handle alignments of 1 MB maximum. As a consequence, running qemu-kvm in valgrind could cause alignment errors. This update modifies the underlying code so that memalign and posix_memalign replacement can now handle alignments up to 4 MB. (BZ#757728)

This update also adds the following enhancement:

  • With this update, valgrind has been updated to provide complete support for IBM POWER7 Series and VPN-1 Power VSX hardware as well as support for Decimal Floating Point (DFP). (BZ#739143)

All users of valgrind are advised to upgrade to these updated packages, which fix this bug add this enhancement.

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 use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258
