Demo > https://cppinsights.io/s/abca4605 I think you are reading the output incorrectly. It creates 2 different closures but of the same type (__lambda_4_17). See https://godbolt.org/z/K17obKdr1 also. That happens also for GCC: (void) std::basic_ostream<char>::operator<< ((struct basic_ostream *) std::basic_ostream<char>::operator<< (&cout, foo (<lambda()>::operator() (&TARGET_EXPR <D.59246, {}>))), foo (<lambda()>::operator() (&TARGET_EXPR <D.59260, {}>))) >>>>>; TARGET_EXPR <D.59246, {}> and TARGET_EXPR <D.59260, {}> are the two temp variables for the closures.
