Reduced testcase:
#include <typeinfo>

template<int>
struct function1
{
  function1(void (*f)(void))
  {
     typeid(int (*)(char&));
  }
};
void inputclassifier(void){}
function1<1> b(inputclassifier) ;

-frepo is only needed to reproduce this.
This has been failing since at least "3.5.0 20040909".

And another testcase, this time with an array:
#include <typeinfo>

struct function1
{
