FIX: Unexpected behavior when you run a generated Visual Studio 2008 Service Pack 1 application that calls the setjmp function or the longjmp function in a source file
- You enable the global optimization option (/Og) by enabling one of the following options:
- You build a Microsoft Visual C++ source file by using Microsoft Visual Studio 2008 Service Pack 1 (SP1).
- The source file calls the setjmp function, the longjmp function, or both functions.
In this scenario, the compiler may use the same stack offset to store different local variables. Therefore, unexpected behavior may occur when you run the generated application.
