Hello, 

I have problem in using OpenMPI 1.4.3 with PGI 11.8. A simple hello-world test program gives segfault and ompi_info gives segfault, sometimes, too. Using a debugger the problem seems to arise from libnuma

I tried to avoid building of maffinity component specifying  --enable-mca-no-build=maffinity,btl-portals but maffinity component seems to be installed anyway: segfault still arises and 

ompi_info |grep maffinity 

gives the result 

MCA maffinity: libnuma (MCA v2.0, API v2.0, Component v1.4.3).
I also tried to specify --without-libnuma, but I had no success. How can I force compilation to completely avoid the use of libnuma. Is there any better solution looking at the stacktrace above?

thanks,
Francesco
