>Description:
ICE on code that is missing a 'typename'. Inclding the 'typename' obviates the problem.
The program is small:
// Compiling this program causes an internal_compilation_error. The
// program is missing a 'typename'. Compiling with '-DAVOID_ERROR'
// causes the missing 'typename' to be included and the compilation
// succeeds.
#include <vector>
template<class T>
struct CreateLeaf {};
template<class T>
struct CreateLeaf<std::vector<T> >
{
#ifdef AVOID_ERROR
typedef typename std::vector<T>::const_iterator Leaf_t;
#else // erroneous
typedef std::vector<T>::const_iterator Leaf_t;
#endif // AVOID_ERROR
};
