That should be floor or "10" - otherwise, it can give "11" which is too large.
(Or and better: Change the "10" to "11" below then "hello worl(d)" fits into
the string.)

Interestingly, it works if one does not use "n" as argument but sets it in the
procedure. One then gets code like:
  *string =  ... __builtin_malloc ( ... MAX_EXPR <n, 0> )

However, if "n" is passed as dummy argument, one has:
  integer(kind=4) D.1865;
  *string = ... __builtin_malloc ( ... MAX_EXPR <D.1865, 0> )
  D.1865 = *nnnn;

Or in other words: The order is wrong.
