Andi has a patch for this IIRC.  But instead of



  /* Watch overflow that might result from insane profiles.  */

  if (time  MAX_TIME * INLINE_TIME_SCALE)

time = MAX_TIME * INLINE_TIME_SCALE;

  gcc_assert (time = 0);



we should deal with the overflow, not ICE on it.  Like by doing



  if (time  0

  || time  MAX_TIME * INLINE_TIME_SCALE)

time = MAX_TIME * INLINE_TIME_SCALE;
