DOCUMENT:Q168379 13-FEB-2002 [visualc] TITLE :BUG: Debugger Does Not Step Over to __finally Code Block PRODUCT :Microsoft C Compiler PROD/VER::5.0,6.0 OPER/SYS: KEYWORDS:kbtool kbVC500bug kbVC600bugkbbuglist ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - The Integrated Debugger, used with: - Microsoft Visual C++, 32-bit Enterprise Edition, versions 5.0, 6.0 - Microsoft Visual C++, 32-bit Professional Edition, versions 5.0, 6.0 - Microsoft Visual C++, 32-bit Learning Edition, version 6.0 - Microsoft Visual C++.NET (2002) ------------------------------------------------------------------------------- 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 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.
