Created attachment 32302

gcc49-pr60457.patch

Perhaps something like this can fix this?  From the patch description it seems
you were after functions only.

Yes, it is obvious.  We will however need to get better origin representation
(supporting early inlined functions and probably also the variable origins as
they apparently can exist) later on if we ever want save debug info with LTO.
