Error serializing big class in DMD 2.064

[jmcabo]

Hello!!

When compiling with DMD 2.064, I can use orange with simple classes, but not with the complex class. Errors show up when compiling.
When using DMD 2.062, I can serialize the same class without problems.

I still couldn't reduce the problem to a small test case, but I thought I'd paste the errors anyways:

How large test case do you have? What about 2.063.2 and 2.064.2, have you tried any of those?

[jmcabo]

I'll try 2.063.2 later today.

And I'm sorry, when I said 2.064 I meant 2.064.2.

I managed to reduce it to this:

    class TwoConsts {
        public const static int FIRST = 1;
        public const static int SECOND = 1;
        public bool someFlag;
    }

Please note that if I comment one of the two constants, the errors go away.
The same happens with:

    class TwoConsts {
        public immutable FIRST = 1;
        public immutable SECOND = 1;
        public bool someFlag;
    }

Ok, thanks, I'll look into it.

[jacob-carlborg]

Just to clarify, you're trying to serialize an instance of TwoConsts?

[jmcabo]

Just to clarify, you're trying to serialize an instance of TwoConsts?

Yes, which is inside another class, ProgramStateInfo. As in:

    class ProgramStateInfo {
         [...]
         TwoConsts obj;
         [...]
    }

    //And then, somewhere else:

    serializer.serialize(programStateInfo);

Thanks for looking into this!!

I just tested with 2.063.2, and it is worse. It prints an error and then DMD crashes:

    Assertion failure: 'type->ty != Tstruct || ((TypeStruct *)type)->sym == this' on line 741 in file 'struct.c'

and a message box is displayed, saying:

    abnormal program termination

If I comment one of the two constants, DMD 2.063.2 compiles just fine. If the two constants equal 1 are present, it crashes.
