Attached Converter.7z (927758 bytes, application/x-7z-compressed): failing c++ source and sh file

Quuxplusone commented 11 years ago 
Reduced test case:

class Atom;

template <typename T> class allocator;
template <typename T, typename A> class vector;

typedef vector<const Atom *, allocator<const Atom *> > AtomVector;

template <typename T, typename A = allocator<const Atom *> > class vector {};

void foo() {
  vector<Atom *> v;
  AtomVector v2(v);
}
