Sorry for the delay, initially I didn't realize why my first report didn't make

about "-ffunction-sections disabled; it makes profiling impossible [enabled by
default]".

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
