When -g is removed, problem is gone.

--- Comment #7 from Markus Trippelsdorf  ---
When one uses a naive test script one arrives at the testcase
from comment 4. Using a differential script (-O2 vs. -flto -O2 -g)
one gets:

markus@x4 /tmp % cat context2.ii
namespace std {
template 
_Tp declval();
}
class A {};
namespace std {
template 
using __allocator_base = A;
template

template >
class I {};
}

template 
class D;
struct F;
namespace detail {
template 
class iterator_adaptor;
template 
class basic_range {
 public:
  template 
  using store_traits = int;
  template 
  operator V() const {}
};
template 
using preferred_iterator_type = decltype(std::declval);
}

template 
class adaptor_range

  detail::iterator_adaptor<

template

Looks like a stack overflow.
