[Bug fortran/30285] gfortran excessive memory usage with COMMON blocks in modules

[anlauf at gmx dot de]

------- Comment #13 from anlauf at gmx dot de  2007-10-22 07:35 -------
I've adjusted the title slightly to refer to the use of
COMMON blocks (in MPICH, OpenMPI) because the problem of
.mod size excursion depends only on the "nesting depth",
not on the actual size of the modules.  I hope this bug
will be fixed someday when somebody has a look either at
the module writing routines or at the way the structures
containing module information are held internally.

I am unable to compile a reasonably large project (just in
terms of the number of files, not total source code size!)
using MPI.
The problem appears even worse with OpenMPI than with MPICH.
