I suspect this will not yield good results when optimization is present.

I normally see this kind of thing as GIGO -- gdb does what the compiler
tells it.  If the compiler thinks a variable is uninitialized at some
PC, it's free to omit that from the location list.

Not always, I think because of inlining.  However I'm not really sure.
Compilers can emit pretty much anything they like.
