RHBA-2013:0347 - valgrind bug fix and enhancement update

Synopsis

valgrind bug fix and enhancement update

Type/Severity

Bug Fix Advisory

Topic

Updated valgrind packages that fix several bugs and add an 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.

The valgrind packages have been upgraded to upstream version 3.8.1, which provides a number of bug fixes over the previous version. (BZ#823005)

This update fixes the following bugs:

  • When running a large program under valgrind, the "Valgrind: FATAL: VG_N_SEGNAMES is too low." error messages could be returned. With this update, the compile time constants have been increased (VG_N_SEGMENTS to 50000, VG_N_SEGNAMES to 25000) and these errors no longer occur. (BZ#730303)

  • Previously, the valgrind gdbserver did not properly report exit or a fatal-signal process termination to the gdb debugger. Consequently, the "Remote connection closed" error messages were returned. This bug has been fixed in the code and the process termination is now properly reported in gdb. (BZ#862795)

  • On IBM S/390 architecture, valgrind could report a "Conditional jump or move depends on uninitialized value(s)" warning message for the tsearch() function in glibc. This update includes a standard suppression for these warning messages, which are no longer reported. (BZ#816244)

This update also adds the following enhancement:

  • The embedded gdbserver has been added to allow integration of valgrind with the gdb debugger. (BZ#672959)

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