Not a know issue.
The first error message isn't very helpful. But the second might
indicate some ptrace operation or reading /proc/pid/mem is not
permitted. Both tests rely on being able to attach to and read from the
process memory to get the ELF image (the first for the vdso, the second
for the deleted.so).
There have been selinux setting that prevented any such operation. Maybe
Arch linux enables something like that?
