[Patch, Fortran] PR 42858 - [4.5 Regression] ICE in gfc_array_dimen_size at ../../trunk/gcc/fortran/array.c:2063

[Tobias Burnus]

I intent to commit the attached patch as obvious unless someone rejects it.

The problem is that the intrinsic check is not done properly. For
generic procedures (expr->symtree->n.sym->attr.generic), the specific
procedure is expr->value.function.{esym,isym}. While "value" is a union,
value.function is a struct and thus checking value.function.esym == NULL
is valid.

Bootstrap and regtested on x86-64-linux.
