Hello Stefan, hello Max, well, then there is an additional 1.19 - issue someone has to look at that differs from the problem showing with 1.18.1 (and I consider this to happen "prior" to the "'pos' undeclared problem", as the address remains stable with and without the patch). This is apparent to me not only because of Stefan and I are having the same findings but because your failures show at identical positions, the adresses you published in #16 are identical (apart from the final "^" what appears to be a typo (?) to me ....) Regards Dieter
