Hi Boyan, Unfortunately I was not able to replicate your bug. I tried with icc and ifort but with MPICH 3.0.4 (I do not have access to Intel’s MPI).
Somehow, in your case, the communicator is getting invalidated. I do not think it has anything to do with the MPIPOSIX driver since there is nothing unusual or complicated going on in there with MPI, but then again, I have no clue what the problem is. If this is the only error reported in make check, then I would not worry about it too much, since the MPIPOSIX driver is very likely to be decommissioned soon. If you would like to explore this further, please ping me off-list with a debug trace as to where the barrier call fails in the library, and perhaps track where the communicator gets invalidated, since I cannot replicate those myself. This might give me a better clue as to what is going wrong.

To answer your questions: I have tried only the Intel MPI and compilers, I have not tried any other compilers and MPI implementations. I am attaching my configure options, in case you need this info. Please let me know if you need any other details from me.
