Here is a reduced testcase: 
------------------------ 
extern double pow (double __x, double __y) throw (); 
extern double sqrt (double __x) throw (); 
extern double sin (double __x) throw (); 
 
void foo(double a2) 
{ 
  double p, q, D, c1, c2, ro1, ro2, fi1, fi2; 
  double x[6][3]; 
  int i; 
 
  p = a2 * a2 / 3; 
 
  if( D < 0 ) 
    c2 = c1; 
  else 
    c2 = q / 2 - sqrt( D ); 
 
  c2 = ( (ro1)<0 ? -1:((ro1)>0?1:0 ) ) * pow(ro1, 1./3.) + 
       ( (ro1)<0 ? -1:((ro1)>0?1:0 ) ) * p / 3. * sin( ro1 ); 
 
  for( i = 0; i < 6; i++ ) 
    if( i < 3 ) 
      { 
        x[i][0] = sin( fi1 / 3.) * c1 - a2 / 3; 
        x[i][1] = sin( fi1 / 3.) * c2; 
      } 
}

This is fixed for 3.4 and mainline, though.
