GCC Bugzilla Bug 35546

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.

Regards
Dirk Zoller

This was probably broken by the attribute handling on templates changes.

CCing Jason as he was the one who did the attribute delaying patches for 4.3.0.

Looking into this.
