>From the C++ standards doc (Latest download form the website) (excerpt listed
below), I thought that member functions could be allowed. I am not entirely
sure if *function* can also refer to *member-function*.


4.  A non-type template-parameter shall have one of the following (optionally
cv-qualified) types:
— integral or enumeration type,
— pointer to object or pointer to function,
— reference to object or reference to function,
— pointer to member., or
— in a constrained template (14.10), a type archetype T for which the
concept requirement std::NonTypeTemplateParamet
   is part of the template’s requirements.


Did I understand this wrong ? Does the correct interpretation of the standard
not allow for member-function-pointers as non-type arguments ?

The following links point to a different interpretation.

Preprocessed test case that causes the compiler error.

[Bug c++/38681] New: Internal compiler error. expr.c:6956 [Template instantiation with non-type value of member function ptr]

[juvvij at gmail dot com]

While trying to reinvent some suitablu smart technique for routing Gtk's static
callbacks to object methods, I thought I had created a suitably brilliant
solution. Gcc could not digest it. While I am looking at smarter solutions from
boost or loki, I would like to see if I really was onto a workable solution.

I'm not sure if the triplet info above is useful enough. The bug posting
guidelines promised eternal shame if I didn't do my very best. So ading more
info, hopefully it is not all wasteful!

I have the as-packaged-for-ubuntu 8.10, g++-4.3.2 version.
