Seems that the ConstantValue attribute for the field "x" is pointing to a
Constant_Integer, not a Constant_Long in the "x = 0" case.  Section 4.7.3 of
the vmspec specifies that it should match the field's type, not the
constant's.

How to fix?  Dunno yet, parse.y is probably missing a promote_type()
somewhere.
