Actually, it turned out the real problem was declaring Depth to be a
scalar variable, but giving it multiple data values.  So the
workaround is declaring

        int Depth(Depth);
        float Oxygen(Oxygen);

since you are providing lots of values for these two variables in the
data section.  It's OK to factor out the type in a list of variables.
So for example, the following works fine:

netcdf bugr {
variables:
        float Depth, Oxygen;
data:
        Depth = 2;
        Oxygen = 5;
}

but the following will trigger the segmentation fault:

netcdf bugr {
variables:
        float Depth, Oxygen;
data:
        Depth = 2, 4;
        Oxygen = 5;
}
