Well, you won first round against me, but that is just like Mike Tyson
knocking out Margareth Thatcher - unfortunately, it is not impressive to
win against me and doesn't lead to any changes. Better raise this in
firebird-devel or whatever and hope someone actually knowing the source
code (e.g. Dmitry Yemanov who answered early in your thread) picks it up
and decides to investigate and change the code in one way or the other.
