        Description

        Bug reported by HP in 1.3.1, but also fails in current 1.4 merlin workspace.
        GC stack crawls cannot handle having the same callee-save register appear more than once in an OopMap. Post-allocate-copy-removal occasionally breaks this invariant for oops on Intel. Can't happen on Sparc since no callee-save registers.
