BUG: Debugger Does Not Step Over to __finally Code Block

ID: Q168379

The information in this article applies to:

The Integrated Debugger, used with:
- Microsoft Visual C++, 32-bit Editions, versions 5.0, 6.0

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.

MORE INFORMATION

Steps to Reproduce Behavior

Compile the following code with debug information.


    #include <iostream.h>

    void main ()
    {
   int counter=0;

    __try {

   counter++;//SET A BREAKPOINT HERE
   cout << "In try block" << endl;

          }

    __finally
          {
      counter++;
      cout << "In finally block" << endl;
          }

    cout << "Exit, counter=" << counter << endl;

    }

Set a breakpoint on the line shown above. Start the debugger with Debug Go or by pressing the F5 key. Step-Over (or, press F10) from that point onward. The debugger exits the program without going to the __finally block.
