error with blacs_gridinit subroutine when some inouts are parameters

I am using Intel Fortrasn (v10), MPI, and MKL. My program declares some parameters but when I use these as inputs to the subroutine blacs_gridinit it crashes. If I change them to normal integer variables and set them within the program code it works ok. All the docs say the inputs are just that (inputs) and not outputs. The parameter version works OK on another machine (Silicon Graphics MPI and scaLapack, Intel Fortran).

I can live with this but I don't like not understanding why there is a problem.

Thanks are any ideas.
