BUG: Debugger Does not Step Over to __finally Code Block

• The integrated debugger included with: - Microsoft Visual C++, 32-bit Editions, version 5.0

SYMPTOMS

The debugger does not Step-Over to code in __finally block from a __try block.

CAUSE

The __finally code is executed via a "call" instead of a "jmp instruction.

RESOLUTION

The workaround is to do a Step-Into (F11 key) instead of Step-Over (F10 key) in the debugger.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. We are researching this bug and will post new information here in the Microsoft Knowledge Base as it becomes available.
