Here, one has for the internal length assignment:
  .__result = 3

The RHS is a simple "3", but the LHS is a pointer to an integer ...

Pilot error of mine: As that code also lacks an ALLOCATE, it is also invalid
without an explicit ALLOCATE statement.

(The real-world program uses an array on the RHS. When the result_string has no
"dimension(:)", it compiled. For both, cf. email.)
