--- Comment #1 from Richard Henderson <rth at gcc dot gnu.org> 2012-11-20 17:08:15 UTC --- The call to get_pointer_alignment_1 at ipa-prop.c:2959 does not do what the author intended. In particular we really really need to notice the "false" return value when the results are conservative, and do nothing.
