[Bug tree-optimization/27753] New: ICE in make_ssa_name on autovect-branch

["gcc at pdoerfler dot com" <gcc-bugzilla at gcc dot gnu dot org>]

/usr/local/vect/bin/g++ -v
Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../gcc-vect/configure --enable-languages=c,c++
--prefix=/usr/local/vect
Thread model: posix
gcc version 4.2.0-autovect 20060518 (experimental)

Reduced testcase below ICEs:
/usr/local/vect/bin/g++ -O3 -ftree-vectorize -march=pentium-m -c vecreduced.cpp
vecreduced.cpp: In member function ?vector<T>& vector<T>::add(T) [with T =
ppoint<int>]?:
vecreduced.cpp:14: internal compiler error: in make_ssa_name, at
tree-ssanames.c:129

========================================================
template <class T>
struct ppoint {
  int x, y;
  inline ppoint<T>& operator+=(const ppoint<T>& p) {
    x+=p.x;
    y+=p.y;
    return *this;
  }
};

template<typename T>
class vector {
public:
  vector<T>& add(T cst) {
    for (int i=0; i<vectorSize_; i++) {
      theElements_[i]+=cst;
    }
    return *this;
  }
private:
  int vectorSize_;
  T* theElements_;
};

template class vector<ppoint<int> >;
