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.

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.
