Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <file:///usr/share/doc/gcc-11/README.Bugs> for instructions.

end, a complete set of source files (see below).
See attachment.
Additionally, here are the contents of the .cpp file I used to trigger this
issue. The included file is from Boost 1.76.0.
#include <boost/asio/async_result.hpp>
#include <memory>
template<typename T>
class Foo {
};
template <typename T>
class Qux {
public:

T a_;
};

template <typename CompletionToken>
decltype(auto) Qux<T>::AsyncOp(
CompletionToken&& token) {
using SignatureType = void();
return boost::asio::async_initiate<CompletionToken, SignatureType>(
[&, this](auto handler)
{
struct Grault : public Foo<decltype(a_)> {};
auto ptr{std::make_shared<Grault>()};
}, token);
}
void corge() {
struct Quux {};
Qux<Quux> qux{Quux{}};
qux.AsyncOp([&]() {});
}
