[Bug rtl-optimization/23714] New: [4.1 Regression] ICE in expand_assignment

[kkojima at gcc dot gnu dot org]

cc1plus -O2 -fnon-call-exceptions fails with

  internal compiler error: in expand_assignment, at expr.c:3929

for

void run (void) {
  float stack[1];
  float *sp = stack;
  try
  {
    float value2 = ((float) *(--sp));
    float value1 = ((float) *(--sp));
    *(sp++) = (value1 - value2);
  }
  catch (int *ex)
  {
  }
}

which is a testcase for PR 23706 written by Andrew Pinski.
It passes on 3.4 and 4.0.
