But even so, the variable should be destroyed when it moves out of scope and it is not, so I suspect some sort of circular reference. I just can't see it.

If $booking_dlg->{booking_main} contains a reference to $booking_dlg? Then this is a circular reference:

$booking_dlg->{Ctl_Booking_Referring_Doctor_Txt} = i_staticText->new($
+booking_dlg->{booking_main}
