In CDL, you need to use a separate declaration for each variable.  It
doesn't allow factoring out the type for a list of variables.  So the
declarations need to look like this:

variables:
        int Station;
        int Month;
        int Day;
        int Year;
        int BottomDepth;
        int BottleNumber;
        int Cast;
        int Depth(Depth);

etc.

Nevertheless, ncgen shouldn't have gotten a segmentation fault when
parsing the CDL you provided, but should have produced an error
message instead.  Thanks for reporting this bug in ncgen.
