[Bug c++/43016] New: Inappropriate multiple definition error for lambda function when inside inline functions

[plaice at cse dot unsw dot edu dot au]

When an inline function f() includes a lambda function and f() is called in
more than one compilation site, a multiple definition error for the lambda
function is generated at link time.  This does not correspond to the standard,
section 5.1.1.5, which states that "the closure type for a lambda expression
has a public inline function call operator".
