There is the following code in ttinterp.c around line 605:

  /* XXX: We reserve a little more elements on the stack to deal safely */
  /*      with broken fonts like arialbs, courbs, timesbs, etc.         */
  tmp = exec->stackSize;
  error = Update_Max( exec->memory,
                      &tmp,   
                      sizeof ( FT_F26Dot6 ),
                      (void**)&exec->stack,
                      maxp->maxStackElements + 32 );
                                               ^^
Please try to increase this value and tell us whether it solves your
problem.
