SYMPTOMS
Consider the following scenario. You create a custom application by using the Microsoft .NET Framework 2.0. Then, you run the custom application on a 64-bit computer. In this scenario, random values may be written to the float parameters of some functions in the custom application.



CAUSE
This problem occurs if the following conditions are true:
 * The just-in-time (JIT) compiler generates code that is not optimized.
 * A method has enough local variables to cause the stack frame to be larger than 4 KB.
 * The first parameter of the function is a floating-point number, or the second parameter of the function is a floating-point number.
