g++ 3.4.1 doesn't accept a static member function as the argument for a non-type template parameter of the appropriate function type. For example, given: <code> template<void (*)()> void tfunc(); struct foo { static void bar(); }; void foo::bar() { tfunc<bar>(); } </code> it says: <error> In static member function `static void foo::bar()': error: `static void foo::bar()' cannot appear in a constant-expression error: template argument 1 is invalid error: no matching function for call to `tfunc()' </error> g++ 3.3.4 accepts the code.
