sigaction(2) broken in -current

[Matthias Drochner <M.Drochner%fz-juelich.de@localhost>]

I'm trying to update my box to -current. With a kernel
from yesterday's sources, a lot of breakage happens due
to sigaction(2) failing unexpectedly. The appended
test program get an EINVAL.
This is a non-modular kernel.

best regards
Matthias

#include <stdio.h>
#include <signal.h>
#include <err.h>

int
main()
{
        struct sigaction osa;
        int res;

        res = sigaction(SIGINT, NULL, &osa);
        if (res)
                err(1, "sigaction");

        return 0;
}
