--- Comment #1 from anlauf at gcc dot gnu.org ---
I cannot reproduce the ICE here, but valgrind tells me that something
is fishy here with error recovery that can be solved by the following
obvious patch:
diff --git a/gcc/fortran/expr.cc b/gcc/fortran/expr.cc
index 5ec369c9cd8..9ab6b8eed86 100644

However, playing some more, I get an ICE when changing in the bad type
declaration
class(c), pointer :: a(2)
to
class(c), allocatable :: a(2)
The traceback tells me that we might want to wait for Paul's finalization
fix...
