Discussion:

The call to `do_put(out, str, fill, (int)val)` in N4582 subclause 28.4.3.3.3 [facet.num.put.virtuals] paragraph 6 cannot select a best viable function in overload resolution given the overloads listed for `do_put` in 28.4.3.3 [locale.nm.put].

There is implementation divergence:

- Some implementations call the `long` overload (as overriden);

- some implementations call the `unsigned long` overload (as overriden);

- some implementations call something else.

It appears that the resolution to DR 359 attempted a fix; however, the relevant portion of the change was not applied to the WP.
