RHBA-2011:0665 - Bug Fix Advisory

Topic

Updated valgrind packages that fix several bugs and add various enhancements are
now available for Red Hat Enterprise Linux 6.

Description

Valgrind is a tool to help users find memory management problems in the
programs. Valgrind can detect a lot of problems that are otherwise very hard to
find or diagnose.

The valgrind packages have been upgraded to upstream version 3.6.0, which
provides several bug fixes and enhancements over the previous version.
(BZ#661245)

This update fixes the following bugs:

• When MySQL Server was run via valgrind, an error in valgrind prevented MySQL

Server from writing to its log file and caused it to return a number of error
messages. This bug has been fixed and MySQL Server now starts up normally when
run via valgrind. (BZ#679906)

• When the snmpd tool was executed under valgrind on the 64-bit PowerPC

architecture, it terminated unexpectedly. This bug has been fixed and the
"valgrind /usr/sbin/snmpd" command now works as expected. (BZ#665289)

This update adds the following enhancements:

• With this update, valgrind now supports IBM POWER 6 and IBM POWER 7 systems.

(BZ#630173)

• With this update, valgrind now supports IBM System z. (BZ#632354)

Users of valgrind are advised to upgrade to these updated packages, which fix
these bugs and add these enhancements.
