Bug Fixes

BZ#1037680

Due to the way the Python programming language was packaged for Red Hat Enterprise Linux, the boost packages could not be provided for secondary architectures. For example, boost-devel.i686 was not available on the x86-64 architecture. The Python packaging has been updated, and it is now possible to install secondary-architecture versions of the boost packages.

BZ#1021004

A coding error in the shared_ptr pointer previously caused a memory leak when serializing and unserializing shared pointers. The shared_ptr code has been corrected and the memory leak now no longer occurs.

BZ#969183

Due to an error in threading configuration of GNU Compiler Collection (GCC) version 4.7 or later, Boost failed to detect the support for multithreading versions of GCC. This patch fixes the error and Boost now detects multithreading support in the described circumstances correctly.

BZ#1108268

Prior to this update, a number of boost libraries were not compatible with GCC provided with Red Hat Developer Toolset. A fix has been implemented to address this problem and the affected libraries now properly work with Red Hat Developer Toolset GCC.

BZ#801534

The mpi.so library was previously missing from the boost libraries. Consequently, using the Message Passing Interface (MPI) in combination with Python scripts failed. With this update, mpi.so is included in the boost packages and using MPI with Python works as expected.

Enhancement

BZ#1132455

The MPICH2 library has been replaced with a later version, MPICH 3.0. Note that Boost packaging has been updated accordingly and new packages are named boost-mpich* instead of boost-mpich2*.
