<pre>Clang's diagnostic is correct. You cannot mention a variable with a deduced
type in its own initializer. See [dcl.spec.auto]p11: "If the name of an entity
with an undeduced placeholder type appears in an expression, the program is
ill-formed."
Something about the generic lambda seems to be confusing GCC and MSVC, and
they're not properly enforcing this rule. ICC / EDG enforces the rule properly,
rejecting this like Clang does.</pre>
