Did you get this behavior even with the -O0 GCC build? Basically, GDB
tells you what's wrong with the executable. For a short explanation, check
this page (http://www.cs.utk.edu/~vose/c-stuff/onlinedocs/gdb_7.html) and
search for "value optimized out".

I made the experience that using -O0 shouldn't produce the "value
optimized out" problem, because the code is not optimized.
