/**
 * This program checks if the compiler doesn't have a certain bug
 * that we encountered when testing C++11 features.
 *
 * This test validates whether a alias can be used to explicitly
 * call a destructor, which is related to DR244 (see
 * http://wg21.cmeerw.net/cwg/issue244)
 *
 * This is partly fixed May 2014 in clang, see
 * http://llvm.org/viewvc/llvm-project?view=revision&revision=209319
 *
 * Currently the using is required, see
 * https://bugs.llvm.org/show_bug.cgi?id=12350
