This is a deliberate change.    From "perldoc perldelta":

     END blocks and the `-c' switch

     Prior versions used to run BEGIN and END blocks when Perl
     was run in compile-only mode.  Since this is typically not
     the expected behavior, END blocks are not executed anymore
     when the `-c' switch is used.


Hmmm..  wait a moment   -  that doesn't actually cover the case you quote.
Seems like the attached doc patch is needed.
