--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
/* When adding a variable-sized variable, we have to handle all sorts
of additional bits of data: the pointer replacement variable, and
the parameters of the type. */
None of this code is expecting base types which have non-constants sizes ....
