--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Use a TMPDIR env if you want to prevent other users from getting access to files. This is a minor security hole really because it allows a person with already have access to do bad things. If you trust an user to have an user account then you have to trust enough not do bad things.
