[OMPI devel] SEGFAULT in mpi_init from paffinity with intel 11.1.059 compiler

2009-12-11 Thread Daan van Rossum
Hi all, There's a problem with ompi 1.3.4 when compiled with the intel 11.1.059 c compiler, related with the built in processor binding functionallity. The problem does not occur when ompi is compiled with the gnu c compiler. A mpi program execution fails (segfault) on mpi_init() when the follo
