Hi!
On the following testcase we ICE because we call dump_global_iord
on the artificial function with file cdtor, and that function uses
input_location, which can be anything at that spot, can be completely
unrelated to that function and can be (as in this case) UNKNOWN_LOCATION,
where LOCATION_FILE is NULL, which pp_printf doesn't like for %s.
Fixed by using DECL_SOURCE_FILE of the cdtor instead.
Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?
