This isn't a bug.
As for this special ctype table, that might be fun to find, but what might be more useful is to make the solaris locale model have the similar functionality as the GNU model.

§22.2.1.1.1/1: concerning std::ctype<>::is:
Returns: do_is(m,c)
Can't be any clearer than that. The function do_is is required by the
standard to be virtual, which means that the actual function called (and
thus the actual semantics of the function is) depend on the dynamic type
of the object. This is, after all, the whole point behind defining the
protected virtual functions -- any other interpretation, and having the
protected interface makes sense.

>Description:
std::ctype<char>::is doesn't call the virtual function
do_is, as required by the standard. This means that
the programmer cannot derive from std::ctype<char>::is
in order to create his own locales (or, since the existing
implementation of the function doesn't work, to provide one
that does).
>How-To-Repeat:
Compile, then look at the output under "Private CType".
