Error: Variable 'length' cannot appear in the expression at (1)
That comes from the specification expression check. The check is called via
resolve_types -> resolve_charlen -> resolve_index_expr ->
gfc_specification_expr
Thus, one needs to somehow distinguish length specifications in the ALLOCATE
from those in a type-declaration statement; I think one needs to modify both
resolve_index_expr (not calling gfc_specification_expr) and resolve_charlen
(not setting specification_expr).
