That's 66 failures. Here's how they break down:

1) 22 failures related to '.nearest' probes. Here's an example of one of those:

====
eval exec stap -p2 --unprivileged -e {probe
process.library("libfoo.so").statement("libfoofunc@libfoo.c:*").nearest {
println ("Hello"); exit (); }} -c ./foo
semantic error: while resolving probe point: identifier 'process' at
<input>:1:7
        source: probe
process.library("libfoo.so").statement("libfoofunc@libfoo.c:*").nearest {
println ("Hello"); exit (); }
                      ^

semantic error: .nearest is only valid with absolute or relative line numbers

Pass 2: analysis failed.  [man error::pass2]
====

Jonathan, should a .nearest probe to a wildcarded line number work?
