can not work with intelmpi

Nobody has claimed this yet.

I build mpiP with intelmpi and icc. It seems allright when i build the libmpiP.so.

But when I run NPB program mg.D.64 with my intelmpi-compiled mpiP, segmentation in mpiPi_init happened.

Have anyone build mpiP with intelmpi?

```
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Backtrace for this error:

=================================
```

My intelmpi version is:
```
which mpirun
/opt/intel/2020/compilers_and_libraries_2020.0.166/linux/mpi/intel64/bin/mpirun
which icc
/opt/intel/2020/compilers_and_libraries_2020.0.166/linux/bin/intel64/icc
```

Start at mpiPi.c:93, where mpiPi_init() reaches MPI_Comm_rank(), and inspect the call from wrappers_special.c:45. Reproduce the segmentation fault with Intel MPI, icc, and the NPB mg.D.64 program. Done means identifying and resolving the Intel MPI compatibility failure, with the program completing without the reported SIGSEGV.
