valgrind enhancement update

Type/Severity

Product Enhancement Advisory

Topic

A Valgrind update that re-bases to upstream version 3.5.0, adds support for
new Intel64/AMD64 instructions, and fixes several bugs is now available.

Description

Valgrind is a tool to help you find memory-management problems in your
programs. When a program is run under Valgrind's supervision, all reads and
writes of memory are checked, and calls to malloc/new/free/delete are
intercepted. As a result, Valgrind can detect a lot of problems that are
otherwise very hard to find/diagnose.

This update re-bases Valgrind to upstream version 3.5.0 (BZ#522330), and
applies several enhancements and fixes including the following:

• Valgrind now supports cmpxchg instructions. This allows Valgrind to
  profile code that uses the Intel cmpxchg instruction.
  (BZ#476271)
  
• The rebase also adds emulation for the 0x67 address-size-override prefix
  and support for multiple 0x66 operand size prefixes. This prevents
  unexpected "unhandled instruction bytes" errors when using Valgrind to
  profile programs that use these prefixes.
  (BZ#515768 and BZ#530165)
  

All Valgrind users should apply this update.

Solution

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

This update is available via Red Hat Network. Details on how to use
the Red Hat Network to apply this update are available at
