            Bug ID: 87893
           Summary: use of an uninitialized variable in error path
           Product: cairo
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: xlib backend
          Assignee: chris at chris-wilson.co.uk
          Reporter: sixtysix at inwind.it
        QA Contact: cairo-bugs at cairographics.org

in _cairo_xlib_font_fini

http://cgit.freedesktop.org/cairo/tree/src/cairo-xlib-render-compositor.c#n967

when _cairo_xlib_display_acquire does not return SUCCESS,
'display' is not initialized:

http://cgit.freedesktop.org/cairo/tree/src/cairo-xlib-display.c#n366

so after BAIL: it is better to use priv->device and not
&display->base
