Message-ID: <cd09bdd10509140817119d56@mail.gmail.com> (raw)

the following script makes stap segfault, it should exit cleanly on
errors (yesterdays cvs)

probe kernel.function("sys_*") {
                if(pid() = $target) log("here");
                log(syscall_name() .
                   "arg0 =" . string(arg0() ) . " " .
                   "arg1 =" . string(arg1() ) . " " .
                   "arg2 =" .  string(arg2() ) );
        }

output:
semantic error: unable to find local 'target' near pc 0xc011cc71:
