[Bug 1526358] Re: xenial/i386 regression: nspawn fails with "Failed to add audit seccomp rule: Bad address"

I now isolated this seccomp failure into a tiny .c file which reproduces this. On amd64 it works: $ gcc -o /tmp/o ~/seccomp-socket-filter.c -lseccomp && /tmp/o SCMP_SYS(socket) == 41 == 29 Success and on i386 it reproduces the error: $ gcc -o /tmp/o ~/seccomp-socket-filter.c -lseccomp && /tmp/o
