Error description
A simple template specialization is used to strip the const qualification from a given type. When a const-qualified multi-dimensional array is used, the const qualification is not removed. === TEST CASE === #include <iostream> template <typename T> struct remove_const { typedef T type; }; template <typename T> struct remove_const <T const> { typedef T type; }; template <typename T> struct test { void operator()() { std::cout << "not const qualified\n"; } }; template <typename T> struct test<T const> { void operator()() { std::cout << "const qualified\n"; } }; int main() { std::cout << "const int[4][2]: "; test<remove_const<const int[4][2]>::type>()(); } $ xlC apar.cpp $ ./a.out const int[4][2]: const qualified $
