FIX: Cannot Watch Local Variables of a __finally Block

MORE INFORMATION

The try-finally statement is a Microsoft extension to the C language that enables applications to guarantee execution of cleanup code when execution of a block of code is interrupted.

You can use the sample code listed below to demonstrate the problem described in this article. You will see the value of the variable 'i' is incorrect in the locals or watch window when stepping through the code of the __finally block.

Sample Code to Demonstrate Problem

/* Compile options needed: /Zi
*/ 

#include <stdio.h>

void main( void )
{
   __try
   {

      // guarded section code...
   }
   __finally
   {
      int i = 2;

      // termination handler code...
      i = 10;
      i = 15;
      i++;
      printf( "In __finally.  i = %d.\n", i );
   }
}
