SYMPTOMS

Consider the following scenario:
  • You create a C++/CLI project by using Microsoft Visual Studio 2005 Service Pack 1 (SP1).
  • The source code in the project executes a throw statement or a _declspec(noreturn) function. The code that is executed after the statement or the _declspec(noreturn) function is run frequently.
  • You build the project with an optimization compiler option enabled. For example, you enable the Maximize Speed (/O2) optimization compiler option. An application is generated after you build the project.
  • An exception is thrown or the _declspec(noreturn) function is executed when you run the application.
In this scenario, a destructor for an unmanaged stack object in the source code is called incorrectly. Additionally, an access violation exception may occur or other unexpected behavior may occur on the application.

CAUSE

The issue occurs because the Command Language Runtime (CLR) code that tries to unwind the stack runs in an incorrect exception handling state.
