--- Comment #1 from Nicholas Krause <xerofoify at gmail dot com> ---
I tried compiling this on both clang trunk and gcc trunk on godbolt. Your
problem seems to be this:
test_lambda([test_uniq = std::move(test_uniq)] {
      test_lambda([test_uniq = std::move(test_uniq)] {});
    })

Your passing into std::move and then again. That's incorrect as your moving and
moving again into the test_lamba. I tried with:

test_lambda([test_uniq = test_uniq.get()]() mutable {
      test_lambda([test_uniq = std::move(test_uniq)] {});
    });

And this does not miscompile due to test uniq getting the actual reference
rather than the r value and going back into another r value reference. This
therefore is not a bug.
