 Incidentally, I believe this test case to be in error.  The type of the 
 argument in the caller and the callee is different.  In particular, the 
 size of the argument is static in the caller and variable in the callee. 
  Whether or not an argument has variable size affects calling 
 conventions, and thus affects how the callee should find the argument in 
 varargs.
 
 A correct test case would have the caller have a variable sized 
 structure as well.
