Thanks to @tbj900 for reporting this issue. - Fix a deadlock issue arising from Open MPI's approach to catching calls to munmap. Thanks to Paul Hargrove for reporting and helping to analyze this problem. - Fix a problem with PPC atomics which caused make check to fail unless builtin atomics configure option was enabled. Thanks to Orion Poplawski for reporting. - Fix a problem with use of x86_64 cpuid instruction which led to segmentation faults when Open MPI was configured with -O3 optimization. Thanks to Mark Santcroos for reporting this problem. - Fix a problem when using built in atomics configure options on PPC platforms when building 32 bit applications. Thanks to Paul Hargrove for reporting. - Fix a problem with building Open MPI against an external hwloc installation. Thanks to Orion Poplawski for reporting this issue. - Remove use of DATE in the message queue version string reported to debuggers to insure bit-wise reproducibility of binaries. Thanks to Alastair McKinstry for help in fixing this problem. - Fix a problem with early exit of a MPI process without calling MPI_FINALIZE or MPI_ABORT that could lead to job hangs. Thanks to Christof Koehler for reporting. - Fix a problem with forwarding of SIGTERM signal from mpirun to MPI processes in a job.

Thanks to Joseph Schuchart for reporting. - Fix a problems MPI_NEIGHOR_ALLTOALL when using a communicator with an empty topology graph. Thanks to Daniel Ibanez for reporting. - Fix a typo in a PMIx component help file. Thanks to @njoly for reporting this. - Fix a problem with Valgrind false positives when using Open MPI's internal memchecker. Thanks to Yvan Fournier for reporting. - Fix a problem with MPI_FILE_DELETE returning MPI_SUCCESS when deleting a non-existent file. Thanks to Wei-keng Liao for reporting. - Fix a problem with MPI_IMPROBE that could lead to hangs in subsequent MPI point to point or collective calls. Thanks to Chris Pattison for reporting. - Fix a problem when configure Open MPI for powerpc with --enable-mpi-cxx enabled.
