minimal example reproducing the issue.
When a surface and the associated device are flush()ed and finish()ed, I
believe that cairo should never write to the device anymore (the documentation
contains sentences such as "This function finishes the surface and drops all
references to external resources. For example, for the Xlib backend it means
that cairo will no longer access the drawable, which can be freed." and "This
function finishes the device and drops all references to external resources.
All surfaces, fonts and other objects created for this device will be finished,
too.").
However, when a recording surface is used as a source for a script surface, the
device appears to be accessed after the resources have been released. See
attached source for reproducing example.</pre>
