// PR c++/8186 // Bug: In f, convert_for_arg_passing wrapped the A TARGET_EXPR in an // ADDR_EXPR for passing by invisible ref. stabilize_throw_expr copied the // resulting pointer into a temporary. cp_convert_parm_for_inlining then // dereferences it and tries to initialize B::am with the INDIRECT_REF, // which calls for a bitwise copy. Which is broken. // { dg-options "-O" } struct A { A(); A(const A&); A& operator=(const A&); }; struct B { A am; B(A a) { am = a; } }; void f () { throw B(A()); }
