[Vala] valac bug: missing array size

[Nor Jaidi Tuah <norjaidi tuah ubd edu bn>]

Compiling the following (valac -c g.vala):
        namespace Nsa {
            public class ClassB {
                public int[] x = {};
        
                public void add() {
                    x += 1;
                }
            }
        }

produces the following error
        g.vala.c:71: error: ‘NsaClassB’ has no member named ‘_x_size_’


Removing 'public' from 'ClassB' or from 'x'
"fixes" the error, but renders ClassB unusable
for a library because non-public names will not
be listed in the generated vapi.

Is this a known bug? Is there a workaround other
than what I stated above?
