[Bug c++/14556] New: ICE with <?= operator

[jakub at gcc dot gnu dot org]

struct S
{
  double d;
  S (double x) { d = x; }
  operator double& () { return d; }
};

double foo (S x, S y)
{
  return x <?= y;
}

causes ICE on any GCC I've tried so far (egcs 1.1.2, 2.96-RH, 3.2.3, 3.3.3, 3.4,
trunk).

Suspending as minimum/maximum operators are deprecated and are going to be removed for 4.1.0.
