static struct vtype$periodic_5th_factory vtab$periodic_5th_factory =
{.$hash=9935896, .$size=0, .$extends=&vtab$field_factory};
...
if (vtab$periodic_5th_factory.create == 0B)
{
vtab$periodic_5th_factory.create = new_periodic_5th_order;
}
field_creator.$vptr = (struct vtype$field_factory *)
&vtab$periodic_5th_factory;
u = VIEW_CONVERT_EXPR<struct class$field_p>(field_creator.$vptr->create
(&field_creator));
is broken. You access struct vtype$periodic_5th_factory via a pointer
of type struct vtype$field_factory but they are not in any way related.
Look into alias.c:record_component_aliases and provide proper BINFOs,
or if that is not possible make sure to disable TBAA for vtables
by making all pointers to them ref-all.
