The following is a bit of a weird way to tell me $filename is a pointer to a string:
$ stap -e 'probe syscall.open.return { log("opened: " . $filename); }'
semantic error: type mismatch (long vs. string): identifier
'_get_kretprobe_long' at
/usr/local/install/systemtap/share/systemtap/tapset/kretprobe.stp:30:10
source: function _get_kretprobe_long:long(i:long) %{ /* pure */
^
Pass 2: analysis failed. Try again with another '--vp 01' option.
Obviously I should have used user_string($filename) here. It is harder to spot
what the real error is in a larger return probe handler which has multiple
string contexts.

--- Comment #3 from Frank Ch. Eigler <fche at redhat dot com> ---
The current error message is pretty good:
% stap -e 'probe syscall.open.return { log("pid: " . pid()); }'
semantic error: type mismatch: expected string but found long: identifier 'pid'
at <input>:1:43
source: probe syscall.open.return { log("pid: " . pid()); }
