So, we're down to crashes in gin_metapage_info() on ia64 and sparc64.
My guess is that the raw page data that is passed into the function
needs to be 8-byte aligned before being accessed as GinMetaPageData.
(Maybe GinPageGetMeta() should do it?) Does anyone have a box like this
handy to experiment? Of course an actual core dump could tell more.
