I think you have a part license (with precompiled dcu), right? If so you
have to wait for Jason's update.

BTW, very similar problem is occuring in Rel3.7:
Params.ByName('ADateField').AsString:='30.07.2002'
will fail even with German date constants. There is a poor implementation of
international date formats in IB_Parse functions. I wasn't able to track
down so I had to switch back to 3.6c
