MMD acting up...

[Cory Spencer]

I've encountered some multimethod dispatch funnyness tonight.  The 
included code which one would expect to produce a value of 1 ends up 
printing a value of 3.

Changing "a" and "b" to be regular Integer types seems to work.  Can 
anybody shed any more light on this?

-c
.sub _main @MAIN
  .local pmc class
  .local pmc a
  .local pmc b
   subclass class, "Integer", "LispInteger"
   a = new "LispInteger"
   b = new "LispInteger"
   a = 1
   b = 1
   print a
   print " * "
   print b
   print " = "
   a = a * b
   print a
   print "\n"
  end
.end
