A while back I tried this for the Linux kernel, with similiar results. I just let it go without investigating further, guessing that maybe some tricks with compiler directives were incompatible with turning off optimization. But there's a good motivation for wanting to turn off optimization. Single-stepping with a debugger at the C source level is almost useless. I've since gotten better at single-stepping at the assembly level while using the mixed c and assembly view of gdb.
