In gcc/unwind-dw2.c,
_Unwind_SetGR()'s third parameter is a _Unwind_Word.
In libstdc++-v3/libsupc++/eh_personality.cc:394:
its third argument is a _Unwind_Ptr.
How does the code guarantee correct alignment for machines where
typedef unsigned _Unwind_Word __attribute__((__mode__(__word__)))
typedef unsigned _Unwind_Ptr \equiv __attribute__((__mode__(__pointer__)))
differ? (See gcc/unwind.h.)
