[Bug c++/19604] New: vtable error with virtual inheritance and tables

["webmyster at addoc dot u-psud dot fr" <gcc-bugzilla at gcc dot gnu dot org>]

I don't know if it's a bug in g++ or a lack in the specifications of C++ ...

I define two classes, one inherited from the second. I allocate a table of the
child, I give it to a fonction that waits for the parent class.

Inside this function, when I try to access virtual functions of an element of
the table other than the first, I get a segfault.
It seems to be that in this function, the size of each element of the table is
considered to be the one of the parent but not the one of the child. That
induces a memory shift that segfault when trying to accessing the vtable ...

Is there the size of the object inside the vtable ?
