I tried to look at this NPE, but was unable to find a fix. However, here is
what I suspect -- maybe it is useful for someone else:
I think the NPE happens in
nqp/src/vm/jvm/runtime/org/perl6/nqp/sixmodel/reprs/CStructInstance.java:95
(within public SixModelObject get_attribute_boxed) with the following code:
o = (Object)Structure.newInstance(structClass, ((Pointer)o));
Four lines above 'o' is created with
Object o = storage.readField(name);
but 'storage.readField(name)' seems to be 'null'. Maybe this is not filled
properly when the Perl 6 object is created?
