--- Comment #5 from Richard Biener <rguenth at gcc dot gnu.org> ---
apD.1859 = &apD.1844;
# .MEM_7 = VDEF <.MEM_3>
# USE = nonlocal null { D.1844 D.1859 } (escaped)
# CLB = nonlocal null { D.1844 D.1859 } (escaped)
_6 = VA_ARG (&apD.1859,
this also looks like double-indirection (and thus wrong-code?)
Note that I'd defer all possible optimization issues to _after_ re-writing
the stdarg pass to take advantage of va_arg not being lowered.
