Subject: [OMPI devel] fortran MPI_COMPLEX datatype broken
From: Jeff Squyres (jsquyres_at_[hidden])

The extent for MPI_COMPLEX is returning 0.

This is causing many the intel Fortran tests to fail, because they
loop over testing types, and MPI_COMPLEX is one of those types.
Specifically, you get a floating point exception because the intel
test computes (size / extent), and extent==0, so it's a division by 0.

I'm not sure where this happened, but it's feels like something in the
new DDT code...?
