--- Comment #1 from Jonathan Wakely  ---
EDG v6.2 also accepts this, but Clang and MSVC don't.

GCC started to accept it at:

PR c++/85092 - C++17 ICE with unused list constructor.

* call.c (conv_binds_ref_to_prvalue): Also count ck_identity
from a TARGET_EXPR.

From-SVN: r259052


I'll confirm it as a regression, since it doesn't look like that intended to
change this case.
