SYMPTOMS
If you build a project that has templated classes, the compiler may generate incorrect assembly code. When this problem occurs, you receive the following error message:

Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention.

This problem may occur if the templated class does not have a default constructor or does not have any private data members.



RESOLUTION
A supported hotfix is now available from Microsoft, but it is only intended to correct the problem that is described in this article.

WORKAROUND
To work around this problem, do any one of the following:
 * Add a default constructor to the templated class.
 * Add a private non-static data member to the class definition.
 * Explicitly create an instance of the template before it is used as a return type for a function.
