RHBA-2011:1026 - Bug Fix Advisory

Topic

An updated valgrind package that fixes various bugs is now available for Red Hat
Enterprise Linux 5.

Description

The valgrind tool helps to detect memory-management problems in programs.

This updated valgrind package includes fixes for the following bugs:

• When testing prelinked programs, valgrind could have crashed due to a

segmentation fault due to a failed assertion. This was caused by the prelink
utility handling the .bss section incorrectly. This update corrects this
assertion so that it no longer fails in the described scenario. (BZ#587338)

• Previously, when compiling a file against the valgrind pub_tool_basics.h

header using gcc, the compilation failed with this error message:

config.h: No such file or directory.

This was caused by the config.h file which was not a part of the valgrind
package, but was required by the pub_tool_basics.h header. The macro from the
config.h file used before was replaced by the __GNUC__ macro. This fixes the
problem and the compilation runs clean. (BZ#649272)

All users of valgrind are advised to upgrade to this updated package, which
resolves these bugs.
