--- Comment #3 from David Smith <dsmith at redhat dot com> ---
It looks like an overloaded function doesn't have to be involved, just a
function call with the right number of arguments but the wrong types:

=3D=3D=3D=3D
# cat ../src/test.stp
#function foo:long(a:long, b:long)
#{
#       return (a + b)
#}

function foo:string(a:long, b:string, c:long)
{
        return sprintf("%s %d", b, a + c)
}

probe begin
{
        println(__inode_vfsmount(1))
        println(foo(1, 2, 3))
}
# stap -p2 ../src/test.stp
semantic error: unknown type in dereference: operator '&' at
