Test c code by running the example cpi.c

>mpiexec -f machinefile -n 2 ~/mpich_build/examples/cpi

I try to recompile and run cpi.c and it still gets the above error. I tried running a simple hello world example that compiles fine in mpicc and I get the same errors. GCC and g++* compilers work fine. I can run the cpi example by ./ just fine. G++ I discovered wasn't working when I tried to configure openmpi, created a link to the library and resolved the error in openmpi. This was after I configured and installed mpich. MPIexec throws same error. mpiexec -f machinefile -n # hostname works fine. So mpiexec is working its something to do when calling c code. 

1. I can try to reconfigure mpich to see if this resolves the error and its a configuration mistake.

2. It seems like this was reproduced in March. http://lists.mpich.org/pipermail/discuss/2014-March/002396.html

    I'm not sure if this was resolved other than modifying code but this is the example and even simple code breaks. 

3. This is a dual core arm processor so I can see if disabling the second core can help since it looks like it is a timing issue. 

Any other ideas?

Thanks,
