[Bug c++/17754] New: [3.4 regression] Static member function not accepted as non-type template argument

[benh at bwsint dot com]

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.
