--- Comment #2 from Martin Jambor <jamborm at gcc dot gnu.org> --- Created attachment 61613 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=61613&action=edit Reduced test-case This is a reduced self-contained (other than the libstdc++ dependency) test-case that I obtained by repeatedly expanding the includes and running cvise on the result that hopefully exhibits the same bug. Compiling it with GCC 14: /home/mjambor/gcc/14/inst/bin/g++ -S -std=c++11 reduced-pythran-err.cpp succeeds while attempting to do so with GCC 15: /home/mjambor/gcc/15/inst/bin/g++ -S -std=c++11 reduced-pythran-err.cpp Fails with a similar error message: reduced-pythran-err.cpp:62:53: error: no match for 'operator==' (operand types are 'std::__tuple_element_t<0, std::tuple<std::iterator<std::random_access_iterator_tag, std::tuple<>, long int, std::tuple<>*, std::tuple<>&> > >' {aka 'std::iterator<std::random_access_iterator_tag, std::tuple<> >'} and 'std::__tuple_element_t<0, std::tuple<std::iterator<std::random_access_iterator_tag, std::tuple<>, long int, std::tuple<>*, std::tuple<>&> > >' {aka 'std::iterator<std::random_access_iterator_tag, std::tuple<> >'})
