4.336. valgrind
Updated valgrind packages that fix several bugs and add an enhancement are available for Red Hat Enterprise Linux 6.
Valgrind is a tool to help users find memory management problems in programs. Valgrind can detect a lot of problems that are otherwise very hard to find or diagnose.
Bug Fixes
- BZ#708522
- When building the valgrind package with macros to prevent application of any downstream patches, the rebuild process failed. This bug has been fixed and valgrind can now be properly rebuilt in the described scenario.
- BZ#713956
- Previously, the JIT (Just in Time Compiler) in some versions of the JDK (Java Development Kit) generated useless, but valid, instruction prefixes, which valgrind could not emulate. Consequently, Java applications running under valgrind sometimes terminated unexpectedly. With this update, valgrind has been changed to emulate instructions even with these useless prefixes, the JVM process now exits properly, and valgrind displays memory leak summary information in the described scenario.
- BZ#717218
- In a Coverity Scan analysis, a redundant check was discovered in one of the backported patches applied to the valgrind package. An upstream patch has been applied to address this issue and the redundant check is no longer performed.
Enhancement
- BZ#694598
- With this update, the valgrind package has been updated to provide support for 64-bit IBM POWER7 Series hardware.
Users of valgrind are advised to upgrade to these updated packages, which fix these bugs and add this enhancement.
