So, we are unable to fix FillChar because it would uncover bugs hiding
in the other places? ;-)
Ok, so how about introducing, say, FillMem procedure, which is
identical to FillChar
except that it has "out" parameter, and deprecation of FillChar?
I always thought that "FillChar" name is somewhat misleading anyway,
so this is a good opportunity to change it.
