 Mine.  The alias-oracle doesn't use PTA information yet.
 

Richard, I'm not sure how familiar you are with the Fortran
standard, so I'll just give a quick note.  The standard forbids 
the aliasing of arguments.  This prohibition is on the 
programmer not the compiler.  Unfortunately, I believe there is
the possibility that a programmer violates this prohibition
and the compiler can't detect the problem.  In principle, you
can assume that the arguments never alias for a Fortran function
or subroutine; unfortunately, we know programmers tend to 
violate this principle.
