In samples/bpf/ there's sockex3* that would exercise it, or
alternatively in iproute2 repo under examples/bpf/ there's
bpf_cyclic.c and bpf_tailcall.c as a prog.

Hm, generally, we should really add a test case also to BPF
selftest suite to facilitate that. I'll likely do that for
the next batch of BPF patches.
