Hi!
A warning regression fix I'm about to post warns (and breaks bootstrap due
to that) on the following spot. Seems it is a copy and paste from
earlier code that mentions the %qD variable instead of talking about
unnamed temporary.
Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

* gimple-ssa-warn-access.cc (pass_waccess::warn_invalid_pointer):
Avoid passing var to warning_at when the format string doesn't
refer to it.
