Are you saying that this program will crash when called? I do not see this compiling with either gcc 12 or 13. We get a warning when compiling but that is it: crash.cpp: In function ‘int main()’: crash.cpp:7:7: warning: ignoring return value of ‘bool __gnu_debug::operator==(const _Safe_iterator<std::__detail::_Node_iterator<int, true, false>, std::__debug::unordered_set<int>, std::forward_iterator_tag>::_Self&, const _Safe_iterator<std::__detail::_Node_iterator<int, true, false>, std::__debug::unordered_set<int>, std::forward_iterator_tag>::_Self&)’, declared with attribute ‘nodiscard’ [-Wunused-result] 7 | it == it; | ~~~^~~~~ In file included from /usr/include/c++/12/debug/unordered_set:48, from /usr/include/c++/12/unordered_set:52, from crash.cpp:2: /usr/include/c++/12/debug/safe_iterator.h:470:7: note: declared here 470 | operator==(const _Self& __lhs, const _Self& __rhs) _GLIBCXX_NOEXCEPT | ^~~~~~~~ -- José Abílio -- lyx-devel mailing list lyx-devel@lists.lyx.org http://lists.lyx.org/mailman/listinfo/lyx-devel
