/**
* 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
