It's a GNU extension to accept a REAL valued start,end,stride.
See resolve.cc:8412
/* Resolve the expressions in an iterator structure. If REAL_OK is
false allow only INTEGER type iterators, otherwise allow REAL types.
Set own_scope to true for ac-implied-do and data-implied-do as those
have a separate scope such that, e.g., a INTENT(IN) doesn't apply. */
bool
gfc_resolve_iterator (gfc_iterator *iter, bool real_ok, bool own_scope)
and resolve.cc:8376.
/* Resolve an expression from an iterator. They must be scalar and have
INTEGER or (optionally) REAL type. */
static bool
gfc_resolve_iterator_expr (gfc_expr *expr, bool real_ok,
I have no idea why this is allowed.
