--- Comment #8 from Eric Botcazou <ebotcazou at gcc dot gnu.org> ---
Ugh, there is some black magic involved with setjmp and SEH:
# ifdef __SEH__
# if (__MINGW_GCC_VERSION < 40702)
# define setjmp(BUF) _setjmpex((BUF), mingw_getsp())
# define setjmpex(BUF) _setjmpex((BUF), mingw_getsp())
# else
# define setjmp(BUF) _setjmpex((BUF), __builtin_frame_address (0))
# define setjmpex(BUF) _setjmpex((BUF), __builtin_frame_address (0))
# endif
# else
# define setjmp(BUF) _setjmpex((BUF), NULL)
# define setjmpex(BUF) _setjmpex((BUF), NULL)
# endif
so the original code would leave the frame pointer misaligned whereas we now
realign it.
