Well, we haven't *got* any other icc-on-ia64 machines AFAICS, so it
could easily be a software problem.
Your remark about padding set off an alarm bell on re-reading --- what
if RelFileNode is padded to 16 bytes on that architecture? Junk in the
padding might break lookups in bgwriter's internal hashtable. But the
Intel docs I can find do not suggest any such thing. Could someone
confirm what sizeof(RelFileNode) is on ia64?
