You might want to fix these warnings. The first one and the last one seem like they could cause nondeterminism.
Also, you shouldn't be adding -I/usr/include/mpi. mpicc will add the right -I option for you (e.g., do you know for sure that your MPI header files are in /usr/include/mpi?). It's useless at best, and harmful at worst (E.g., if some other MPI implementation is installed into /usr/include/mpi).

I notice that you're not including -Wall and a bunch of other compiler flags in the non-MPI install.
I also notice that you're not compiling the same .c files at all.
So if I'm understanding this thread right -- and I may well not be -- it seems like you're saying:
- when I use gcc to compile main.c, the program runs file
- when I used mpicc to compile ../src/snd_0.1.c, the program fails
If that's the case, your comparing apples to oranges here.
