Source code (no includes needed, no preprocessor involved at all)
------------------------------------------------------------------------
template <int N>
class T
{
void operator() (char const * ...) __attribute__((format(printf,2,3)));
};
template class T<3>;
------------------------------------------------------------------------
This compiles fine with many different gcc versions up to
including gcc-4.2.2 and does not compile with gcc-4.3.
Error messages and details of compiler below.
