[Bug c++/110122] [13/14 Regression] using an aggregate with a member variable with a user defined copy constructor in a class NTTP causes capture and use of the `this` pointer in a generic lambda to produce the following error "-copy ctor- used before its definition"

Very cool, thanks, since your test case seems to cause problems in GCC 11 and
GCC 12 does that mean the bug goes deeper than I thought?

Is that what you meant here btw, that since your second test case triggers the
bug in 11 and 12 that it belongs as a different regression test?

Sadly, the workaround doesn't work when `Bar` is a class template.

So it doesn't work in my specific case :(

I'm still very impressed that you found another way to trigger it as well as a
workaround, it's just a shame I can't use it.
