* compilers for the ARM platform fail to pass structs and classes of certain
* size per value. This seems to be a known compiler bug. For other processors
* (e.g. x86) the error doesn't occur.
* (The ARM compiler creates a temporary object from teststr on the stack, to
* pass it to the helper function. It uses the copy constructor for this.
* After this the temporary object is copied to another place on the stack.
* The result is that the _M_finish pointer then points to the wrong buffer
* end and the size of the short string is incorrectly calculated.)
