That this works in Delphi is a Delphi-bug. TField.Size should contain
the amount of decimals, which is really 0 for an integer. But it seems
like that most components-developers don't know this, and the Delphi-bug
is that it is not enforced. It's the DataSize property that has to be 8
(or 4).
FPC has the same bug in all released versions. I changed the behaviour
in fpc 2.3.1 to see what happens. It was merged to fixes too, though.
I'll look how to fix this without removing the call to CheckTypeSize
completely. (Maybe ignore invalid values for those fields where it
doesn't matter, like integer-fields)
