With the ekopath (aka pathscale) 5.0.5 and 6.0.527 compilers I get an ICE (Internal Compiler Error) building this rc. While this is clearly not an OMPI bug, it may be worth recording in the README.
The (different) errors for these two compilers are shown below. -Paul libtool: compile: pathcc -DHAVE_CONFIG_H -I. -I/sandbox/hargrove/OMPI/openmpi-2.0.0rc2-linux-x86_64-eko-5/openmpi-2.0.0rc2/ompi/mca/pml/ob1 -I../../../../opal/include -I../../../../ompi/include -I../../../../oshmem/include -I../../../../opal/mca/hwloc/hwloc1112/hwloc/include/private/autogen -I../../../../opal/mca/hwloc/hwloc1112/hwloc/include/hwloc/autogen -I../../../../ompi/mpiext/cuda/c -I/sandbox/hargrove/OMPI/openmpi-2.0.0rc2-linux-x86_64-eko-5/openmpi-2.0.0rc2 -I../../../.. -I/sandbox/hargrove/OMPI/openmpi-2.0.0rc2-linux-x86_64-eko-5/openmpi-2.0.0rc2/opal/include -I/sandbox/hargrove/OMPI/openmpi-2.0.0rc2-linux-x86_64-eko-5/openmpi-2.0.0rc2/orte/include -I../../../../orte/include -I/sandbox/hargrove/OMPI/openmpi-2.0.0rc2-linux-x86_64-eko-5/openmpi-2.0.0rc2/ompi/include -I/sandbox/hargrove/OMPI/openmpi-2.0.0rc2-linux-x86_64-eko-5/openmpi-2.0.0rc2/oshmem/include -I/sandbox/hargrove/OMPI/openmpi-2.0.0rc2-linux-x86_64-eko-5/openmpi-2.0.0rc2/opal/mca/hwloc/hwloc1112/hwloc/include -I/sandbox/hargrove/OMPI/openmpi-2.0.0rc2-linux-x86_64-eko-5/BLD/opal/mca/hwloc/hwloc1112/hwloc/include -I/sandbox/hargrove/OMPI/openmpi-2.0.0rc2-linux-x86_64-eko-5/openmpi-2.0.0rc2/opal/mca/event/libevent2022/libevent -I/sandbox/hargrove/OMPI/openmpi-2.0.0rc2-linux-x86_64-eko-5/openmpi-2.0.0rc2/opal/mca/event/libevent2022/libevent/include -I/sandbox/hargrove/OMPI/openmpi-2.0.0rc2-linux-x86_64-eko-5/BLD/opal/mca/event/libevent2022/libevent/include -g -finline-functions -fno-strict-aliasing -pthread -c /sandbox/hargrove/OMPI/openmpi-2.0.0rc2-linux-x86_64-eko-5/openmpi-2.0.0rc2/ompi/mca/pml/ob1/pml_ob1_component.c -MD -MF .deps/pml_ob1_component.TPlo -fPIC -DPIC -o .libs/pml_ob1_component.o Signal: Segmentation fault in VHO Processing phase.
