+Setting an C<ISA> glob to an array reference now properly adds
+C<isaelem> magic to any existing elements.  Previously modifying such
+an element would not update the ISA cache, so method calls would call
+the wrong function.  Perl would also crash if the C<ISA> glob was
+destroyed, since new code added in 5.23.7 would try to release the
+C<isaelem> magic from the elements.  [perl #127351]
