[OMPI users] Segmentation fault in mca_btl_tcp

Hi, We are using openmpi 1.4.1 on our cluster computer (in conjunction with Torque). One of our users has a problem with his jobs generating a segmentation fault on one of the slaves, this is the backtrace: [cstone-00613:28461] *** Process received signal *** [cstone-00613:28461] Signal:

Hi, It seems Microsoft C++ compiler could recognize what the code wants to do, while Intel C++ compiler couldn't. I know a solution for this kind of problem, but it involves some code base changes, I need some time to test it. At moment, if you want to use Intel C++ compiler, the dirty
