$ cat test.ii
# 1 "bad.h" 1
template <class A> struct MisplacedDbg;
# 1 "good.cc"
struct Arg;
typedef MisplacedDbg<Arg> Typedef;
template<typename T> struct Base  {
  virtual ~Base() {
  }
};
template <class A> struct MisplacedDbg : public Base<int> {
};
static MisplacedDbg<Arg> static_var;
$ g++-4.6svn -c -g test.ii
$ objdump -d -l test.o|grep -B2 'bad.h:1'

This causes problems for Gold's ODR violation detector.
