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