Using your example script: $ ./618524 /tmp /tmp $ ./618524 /tmp/ /tmp $ ./618524 /tmp/foo /tmp/foo $ ./618524 /tmp/foo/ Use of uninitialized value $r in concatenation (.) or string at ./618524 line 10. In other words, undef is returned if a path including a non-existent directory followed by further components is included. The behaviour of the function is not well-defined in this case by the document, so this is at worst a documentation bug. Downgrading severity accordingly.
