------- Comment #3 from bangerth at dealii dot org  2005-11-23 17:12 -------
Here's a much shorter testcase:
---------------------
#include <vector>

struct Point {
    Point (const Point &);
    Point (const double x);
    double values[3];
};

Point::Point (const double x) {
  this->values[0] = x;
}

Point::Point (const Point &p) {
  for (unsigned int i=0; i<3; ++i) values[i] = p.values[i];
}

struct X {
    void bar (const std::vector<Point> &vertices);
};

void foo (X &x) {
  const Point vertices[2] = { Point(1), Point(1), };

  x.bar (std::vector<Point>(&vertices[0], &vertices[2]));
}
----------------------

deal.II/deal.II> c++ -c -O3 -funroll-loops x.cc
x.cc: In function 'void foo(X&)':
x.cc:25: error: insn does not satisfy its constraints:

    (nil))
