If you want the compiler to catch this, I don't see any way without requiring the code to indicate specifically which local variables it intends to use, or not using the locals at all by using a seperate cleanup function (as discussed elsewhere in this thread). With information about the locals you might be able to conjure some GCC macros to set things up to complain if you use anything else.
I wonder how difficult it would be to teach e.g. clang static analyzer to catch this, rather than the compiler.
