Semantics of MODIFY_EXPR with CONSTRUCTOR rhs

[Richard Kenner]

    I suspect the failure due to variable-sized temporaries that you saw
    has to do with a think-o in the loop that initialized the elements --
    it should have recursed for nested constructors rather than creating a
    new <MODIFY_EXPR <obj> <CONSTRUCTOR>> statement.

No such luck.  Try compiling the RTS file a-direct.adb.

I'm investigating too ...
