Hi all,

attached patch fixes a memory leak when a user-defined function returns a
polymorphic type/class. The issue was, that the polymorphic type was not
detected correctly and therefore the len-field was not transferred correctly.

Regtests ok x86_64-linux/Fedora 39. Ok for master?

Regards,
	Andre
