+// override the default throwing new operator with a user operator with an empty throw()
+// clause, the MS Visual C++ compiler warns for every non-empty throw clause like
+// throw(std::bad_alloc) that it will ignore the exception specification. The following
+// operator definitions have been checked to correctly work with all currently supported
+// compilers and they should be upwards compatible with C++11/14. Therefore
