            * iresolve.cc (gfc_resolve_adjustl, gfc_resolve_adjustr): if
            string length is deferred use the string typespec for result.
            * resolve.cc (resolve_assoc_var): Handle parentheses around the
            target expression.
            (resolve_block_construct): Remove unnecessary static decls.
            * trans-array.cc (gfc_conv_expr_descriptor): Guard string len
            expression in condition. Improve handling of string length and
            span, especially for substrings of the descriptor.
            (duplicate_allocatable): Make element type more explicit with
            'eltype'.
            * trans-decl.cc (gfc_get_symbol_decl): Emit a fatal error with
            appropriate message instead of ICE if symbol type is unknown.
            (gfc_generate_function_code): Set current locus to proc_sym
            declared_at.
            * trans-expr.cc (gfc_get_expr_charlen): Retain last charlen in
            'previous' and use if end expression in substring reference is
            null.
            (gfc_conv_string_length): Use gfc_conv_expr_descriptor if
            'expr_flat' is an array. Add post block to catch deallocation
            of temporaries.
            (gfc_conv_procedure_call): Assign the parmse string length to
            the expression string length, if it is deferred.
            (gfc_trans_alloc_subarray_assign): If this is a deferred string
            length component, store the string length in the hidden comp.
            Update the typespec length accordingly. Generate a new type
            spec for the call to gfc_duplicate-allocatable in this case.
            * trans-io.cc (gfc_trans_transfer): Scalarize transfer of
            deferred character array components.
