------- Comment #2 from tkoenig at gcc dot gnu dot org  2010-02-14 12:38 -------
The problem appears to be a lack of a backend_decl with
-fwhole-file:

------- Comment #5 from dominiq at lps dot ens dot fr  2010-03-20 11:22 -------
Revision 157552 does not fix the ICE for gfortran.dg/dynamic_dispatch_5.f03
with -fwhole-file on the fortran-dev branch:

/opt/gcc/work/gcc/testsuite/gfortran.dg/dynamic_dispatch_5.f03:32:0: internal
compiler error: in gfc_create_module_variable, at fortran/trans-decl.c:3393

Problem is slightly different on fortran-dev, as Dominique says in comment #5.
