When we use SEH with __finally block,
if we do return in __try block, it causes a local unwind.

To Local unwind, the system need to approximately 1000 instructions.
The local unwind causes a warning C6242. MSDN suggests using __leave keyword(with saving a return value).

But I don't think it's a good idea.
If we save a return value and leave the block, there will be many mistakes.

Is the waring really necessary?
What do you prefer?

Why standard C++ doesn't respect system (foreign or hardware) exceptions? E.g. when null pointer dereference occurs, stack isn't unwound, destructors aren't called, and RAII doesn't work. The common advice is "to use system API". But on certain systems, specifically Win32, this doesn't work. To… >>> More
