One important piece I forgot to add -- I'm running "Hardened Gentoo GCC"
which enables PIE by default [1] [2]. As such, this might explain why other
are (presumably) not seeing this problem.
BTW, I cannot find my original submission on patchwork. Was that e-mail OK?
I see it in the ML archive [3].
With kind regards,
Jan
