That worked like a charm, thank you!
with desired_complex_alignof manually set to 8, that is. Right now it
is set to sizeof(natural_t) -- i.e. 4. Should we change it to
alignof(uintptr_t) or something like that?
Yes, I just sent two patches to do that. As a bonus, we also ensure the 64 bit kernel is free of undefined behavior when built for a 32 bit userland.
