FIX: A program that is developed by using Visual C++ 2005 may close unexpectedly when an exception occurs on the IA-64 platform

A program that is developed by using Microsoft Visual C++ 2005 may close unexpectedly when an exception occurs. This problem occurs if the following conditions are true:
  • The platform is IA-64.
  • The program uses a C++ exception handling mechanism.
  • A function catches an exception that is thrown by another module.
  • When you compile the function that catches the exception, you use the /GS option. Additionally, the function that catches the exception requires a buffer security check.
  • The try-catch statement that handles the exception is not nested within another try-catch statement.

To work around this problem, use one of the following methods.

Method 1

Avoid throwing C++ exceptions across DLL boundaries.

Method 2

Wrap every cross-DLL call in a function that passes only the cross-DLL call. Then, make sure that you use the /GS- option when you compile the function.

Method 3

Enclose the cross-DLL call in an additional try-catch statement that never catches anything.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
