Eugeniy Meshcheryakov reports the following ICE:

(sid)26008:tbm@em64t: ~/src] /usr/lib/gcc-snapshot/bin/g++ -c 2.ii
2.ii: In member function 'void dwflpp::translate_location()':
2.ii:18: internal compiler error: canonical types differ for identical types
void ()(const char*, ...) and void ()(const char*, ...)
Please submit a full bug report,
with preprocessed source if appropriate.


His testcase:

void c_translate_location (
           void (*fail) (
           const char *fmt, ...)
           __attribute__ ((noreturn,
             format (printf, 1, 2)))
           );


struct dwflpp
{
  static void loc2c_error (const char *fmt, ...)
  {
  }

  void
  translate_location()
  {
    return c_translate_location (&loc2c_error);
  }
};
