MPI code error raises a question

With a little help from my friends I have found the error in my MPI code 
that was bedeviling me with Heisenbugs.  One of the arguments to 
MPI_RECV is an integer array status(MPI_STATUS_SIZE).  In one place I'd 
forgotten to make it an array, and just declared it as integer. 
Interested consequences followed from this little mistake.

I'm wondering if this is the kind of error that a compiler might be able 
to detect.
