"Value optimized out" is when the compiler assumes a value is constant and starts hardcoding it instead of reading it from memory. For example:
The compiler can see that nothing else ever assigns a value to x, and if told to optimize the code, will assume it to be a constant value. Knowing this, the compiler may create code like ADD $Y, 5 instead of ADD $Y, $X which has the advantage of not needing to read the value of X from memory every loop.
Having gone this far it may decide that there's no reason for x to actually exist at all, and remove it. Hence value optimized out. Even if it does leave it around you may be in for a suprise when you poke in changes with your debugger; this hardcoded optimization would ignore it.
So it may be that trying to debug an optimized executable is causing all this missingness. Try recompiling with -O0 and see if anything comes back.
