/* When compiled with -pedantic, this program will cause an ICE when the
   constant propagator tries to set the value of *str to UNDEFINED.
   
   This happens because *str is erroneously considered as a store alias.
   The aliasing code is then making *str an alias leader for its alias set
   and when the PHI node at the end of the while() is visited the first
   time, CCP will try to assign it a value of UNDEFINED, but the default
   value for *str is a constant.  */
