[DUB][scid] test crashes

You might want to reduce this using dustmite.

dustmite don't work for me on OS X =(. Anyway there is reduced test:

cdouble bar;
ref cdouble foo()
{
    return bar;
}

Could you please check if the problem is still present? On Linux/x86_64 it was solved with the new ABI code (#768).

Compiled with master just now

Could you please try with master again? The problem seems to be cause by DtoAggrPairSwap which is gone with a65f001.

Fixed. Thanks!
