Comment(by wgmitchener):

 Sorry, formatting of the last message went wrong:
 createAdjustor calls allocateExec (rts/sm/Storage.c) which calls
 ffi_closure_alloc. So in createAdjustor, line 381, we should have (if I'm
 reading the libffi documentation correctly):

 adjustorStub is a pointer ''in data address space'' to the adjustor stub

 code is a pointer ''in code address space'' to the very same spot in
 memory

 and the relative call needs to be calculated in code address space
