In the meantime, here is a patch which fixes a regression I introduced
when fixing a regression with a memory leak. The important thing
here is to realize that we do not need to finalize (and deallocate)
multiple times for the same expression and the same component
in the same namespace. It might cause code size regressions, but
better big code than wrong code...
This is a regression all the way down to gcc 8. OK for all affected
branches?
Ping?
Unless there are any objections, I would commit this to master
on Sunday.
Regards
Thomas
