Unfortunately, this relaxation seems to be insufficient. The only x86 GNU/Linux instance I've seen where strace-k.test fails is i686 Fedora rawhide: https://kojipkgs.fedoraproject.org/work/tasks/3725/7043725/build.log (built from https://sourceforge.net/p/strace/code/ci/ldv/unwind/~/log/) tests$ ../strace -e getpid -k ./stack-fcall getpid() = 3372 > [vdso](+0x0) [0x430] > /usr/lib/libc-2.19.90.so(__libc_start_main+0xde) [0x17e8e] > /builddir/build/BUILD/strace-4.9/tests/stack-fcall(_start+0x21) [0x35c] +++ exited with 0 +++ -- ldv
