'd:\backend\src\P2\main.c', line 413)
Please choose the Technical Support command on the Visual C++ Help menu, or

RESOLUTION
==========
Instead of calling typeid with a temporary object, create a stack object and
then call typeid, referencing the stack object.
STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the
beginning of this article. This bug was corrected in Visual C++ version 5.0.
MORE INFORMATION

Sample Code
-----------
/* Compile options needed: none
*/
#include <typeinfo>
struct X {
X() {};
~X() {};
};
// This main function will cause the error.
void main()
{
const type_info& t = typeid(X());
}
// For the workaround, replace main above with the following:
void main()
{
X y;
const type_info& t = typeid(y);
}
