process return probes not available with inode-based uprobes

[agentzh]

Hello!

I'm trying systemtap 1.8 (from yum) and 2.0-14916 (from git) on Fedora
17 and I'm getting the following error when trying to specify a
user-space function return probe:

semantic error: while resolving probe point: identifier 'process' at
/tmp/QX2q_gw.stp:2:7
        source: probe
process("nginx").function("ngx_http_lua_process_args_option").return {
println("Fire ", pp()) }
                      ^

semantic error: process return probes not available with inode-based uprobes

Any suggestion to avoid this? Sorry if this question has been asked
before, but I fail to find an anwser in Google :(

Thanks in advance!

Best regards,
