The file

http://www.mpq.mpg.de/Theorygroup/CIRAC/people/ripoll/Tensor_diag_z.i

compiled with

g++ -Wall -pipe -fpreprocessed -g -O2 -march=pentium4 -fpreprocessed -c
Tensor_diag_z2.i -o Tensor_diag_z.o

causes the compiler to break down with the following error message

/home/jlr/afs/src/mpscxx/tensor/Tensor_diag_d.cpp: In function

------- Comment #3 from pinskia at gcc dot gnu dot org  2005-10-14 12:05 -------
Here is the source for the 4.1 regression:
      typedef __complex__ double cdouble;
  inline cdouble to_complex(const double &r, const double &i = 0.0) {
     cdouble z;
     __real__ z = r;
     return z;
 }
  template<class value_type, bool simple_copy = true, bool atomic = true> class
RefPointer {
  };
       template<typename elt_t>   class Vector : public RefPointer<elt_t> {
    public:     typedef elt_t number;
      static elt_t elt_zero();
    };
    template <typename t> inline t min(t a, t b) {
 }
    template<> inline cdouble Vector<cdouble>::elt_zero() {
 return to_complex(0.0);
 }
    template<typename elt_t>   class Tensor : public Vector<elt_t> {
   };
    cdouble trace(const Tensor<cdouble> &t) {
     cdouble output = t.elt_zero();
 }

----
Note There are two problems here, one for 4.1 and one for 4.0.

I filed that as PR 24365 as it is not reproducible on the 4.0 branch.

------- Comment #5 from pinskia at gcc dot gnu dot org  2005-10-14 12:19 -------
Reduced testcase for 4.0 at -O0 and 4.1 at -O1:
 typedef unsigned int size_t;
       typedef __complex__ double cdouble;
   template<class value_type, bool simple_copy = true, bool atomic = true>
class RefPointer {
   };
        template<typename elt_t>   class Vector : public RefPointer<elt_t> {
     public:     typedef elt_t number;
       static elt_t elt_zero();
      const elt_t *pointer() const;
     };
     template <typename t> inline t min(t a, t b) {
  }
     template<typename elt_t>   class Tensor : public Vector<elt_t> {
     public:     typedef Vector<elt_t> vector;
         size_t columns(void) const;
         size_t rows(void) const;
    };
     cdouble trace(const Tensor<cdouble> &t) {
      const size_t r = t.rows();
      const size_t c = t.columns();
      cdouble output = t.elt_zero();
      const cdouble *data = t.pointer();
      for (size_t i = 0, j = min(r,c);
  j--;
  i += (r+1)) {
  output += data[i];
     }
      return output;
  }

------- Comment #6 from pinskia at gcc dot gnu dot org  2005-10-14 13:37 -------
Fully reduced testcase:
typedef __complex__ double cdouble;
cdouble elt_zero();
const cdouble *pointer();

cdouble trace(void) {
  cdouble output = elt_zero();
  const cdouble *data = pointer();
  output += data[1];
  return output;
}
----
This works with the C front-end but not with the C++ front-end.

Are those new problems related to c++/21210?

No, these new problems are all midlde-end bugs relating to RETURN_DECL not
being handled correctly (or at all).

I have the simple/obvious patch which fixes this one at least the issue in this
PR and not the one in PR 24365 so this will still not work on the mainline.
