--- Comment #2 from Steve Ellcey <sje at cup dot hp.com> 2011-04-27 21:58:53 UTC --- It looks like I was wrong about this showing up on IA64 Linux. I am only seeing it on IA64 HP-UX and only in 32 bit mode. That probably means it is related to the HP-UX pointer extension (addp4). Do you have access to an HP-UX system?
