I am trying to develop a flutter app which connects to the server and exchanges data using websocket. The server is in .Net Core and using Asp.Net Core Websockets to implement this functionality. The problem I am facing is, my flutter app is not able to connect to the server and throws following error. E/flutter (31498): [ERROR:topaz/lib/tonic/logging/dart_error.cc(16)] Unhandled exception: E/flutter (31498): WebSocketChannelException: WebSocketChannelException: WebSocketException: Connection to 'http://127.0.0.1/client#' was not upgraded to websocket E/flutter (31498): #0 new IOWebSocketChannel._withoutSocket.<anonymous closure> (package:web_socket_channel/io.dart:83:24) E/flutter (31498): #1 _invokeErrorHandler (dart:async/async_error.dart:13:29) E/flutter (31498): #2 _HandleErrorStream._handleError (dart:async/stream_pipe.dart:286:9) E/flutter (31498): #3 _ForwardingStreamSubscription._handleError (dart:async/stream_pipe.dart:168:13) E/flutter (3149...

This question already has an answer here: Observing weird behavior with 'auto' and std::minmax 1 answer structured bindings with std::minmax and rvalues 2 answers Consider following code: #include <cstdint> #include <algorithm> std::uintptr_t minPointer(void *first, void *second) { const auto pair = std::minmax( reinterpret_cast<std::uintptr_t>(first), reinterpret_cast<std::uintptr_t>(second) ); return pair.first; } and the assembly generated by GCC8 with -O3 on https://godbolt.org/z/qWJuV_ for minPointer: minPointer(void*, void*): mov rax, QWORD PTR [rsp-8] ret which clearly does not do what is intended by the code creator. Is this code causing some UB or is it GCC(8) bug? This is UB, but not for the reason you might think. The relevant signature o...
