I have included several VM macros inside my application. I have made sure that I have not nested any macros, but when I load my application in WinLicense user interface, I get a nested macros message. What's wrong?

If you have not inserted nested macros and you get that message, you might be facing a compiler optimizations issue. Some compilers remove the VM_END marker when they are at the end of a procedure (or after a "return" statement) because the VM markers are in fact dummy code that might be affected by compiler optimizations.

Please, make sure that you avoid putting the VM_END marker after a "return" statement or as the last instruction in a function/procedure.

You can also disable local optimizations. In C/C++, you can disable local optimizations. Example:

#pragma optimize("", off)

void MyFunction(void)

{

VM_START

// your code

VM_END

}

#pragma optimize("", on)
