Querytool Beta 20.1.537 / itgenclr009 / Loop statement broken on the Invantive interpreter

Good morning,
it seems that something is broken in Querytool Beta 20.1.537.
a simple loop statement like

declare
     l_test integer := 0;
begin
      for i in 1..10 loop
      l_test := l_test + 1;
      end loop;
end;

will end with a itgenclr009 error.

I don’t see the issue with .529, that means there is a tweak inserted in between .529 and .537

Also it seems impossible to roll-back for downloading previous versions like .529 (I have a machine where only .537 is installed, I wanted to install .529).
May be you should keep links of previous version somewhere ?

Thanks

the issue does not appear with PROD 20.2.27.
