             Bug #: 14589
           Summary: Assertion `Loc.isValid() && "point of instantiation
                    must be valid!"' failed
           Product: clang

Clang built from recent release_32 branch (rev. 169987) aborts with a failed
assertion for me:

> $ cat test.cc
> template<typename> struct S1 {};
> struct S2 {
>     S2(int = 0);
>     S2(S1<void>);
> };
> template<typename> void f1() { new S2(); }
> void f2() { f1<void>(); }
