The patch tries to patch cp/tree.c:build_aggr_init_expr().
build_aggr_init_expr() wraps a ctor-calling CALL_EXPR tree node with an
AGGR_INIT_EXPR tree node, whose expression type is always VOID_TYPE. When
it determines whether the routine being called is a ctor or not, it only
looks into simple cases, but not the case of overloaded ctors in a tree
of COMPONENT_REF (INDIRECT_REF (something, BASELINK (OVERLOAD))). This
patch expands the is_ctor determining logic.

I don't understand how we can get here without having already done overload resolution. At this point we should have a simple function pointer.
