[clang-tidy] crash in cppcoreguidelines-owning-memory when capturing unique_ptr in lambda #106444

Closed deeedob closed 1 month ago

deeedob commented 1 month ago

Hey, this just happened to me on:

clangd --version clangd version 18.1.3 (https://github.com/llvm/llvm-project c13b7485b87909fcf739f62cfa382b55407433c0) Features: linux+grpc Platform: x86_64-unknown-linux-gnu

I could boil it down to the following: 

#include <memory>

int main(int argc, char* argv[])
{
    const auto uptr = std::make_unique<int>(250);
    [uptr](){
    }();

    return 0;
}

this code instantly crashes clangd with signal 11. It has to be something specifically about {unique, smart}_ptrs? no crash when capturing primitives at least...

It's the cppcoreguidelines-owning-memory option that produces the crash

Hey, this just happened to me on: clangd --version clangd version 18.1.3 (https://github.com/llvm/llvm-project c13b7485b87909fcf739f62cfa382b55407433c0) Features: linux+grpc Platform: x86_64-unknown-linux-gnu I could boil it down to the following: ```c++ #include <memory> int main(int argc, char* argv[]) { const auto uptr = std::make_unique<int>(250); [uptr](){ }(); return 0; } ``` this code instantly crashes clangd with signal 11. It has to be something specifically about {unique, smart}_ptrs? no crash when capturing primitives at least...

Could you please try 19 or main branch?

deeedob commented 1 month ago

Tried on:

clangd version 20.0.0git (https://github.com/llvm/llvm-project 5b41eb3a6dcd92711b4adf946e4d9d29c3886007) Features: linux+grpc Platform: x86_64-unknown-linux-gnu

still crashes

HighCommander4 commented 1 month ago

Can you also specify what standard library version are you using? (If unsure, perform go-to-def on <memory> and post the full path of the opened file.)

deeedob commented 1 month ago

libstdc++ 14.2.1, I thought it will take the llvm stl though. Clang is at least set as compiler. compile_commands.json is using clang though: 

{

  "output": "CMakeFiles/cpp_preset.dir/main.cpp.o"
}
HighCommander4 commented 1 month ago

I can reproduce this crash. It's not specific to clangd, it occurs when running clang-tidy --checks=cppcoreguidelines-owning-memory on the command line as well.

Hey, this just happened to me on: clangd --version clangd version 18.1.3 (https://github.com/llvm/llvm-project c13b7485b87909fcf739f62cfa382b55407433c0) Features: linux+grpc Platform: x86_64-unknown-linux-gnu I could boil it down to the following: ```c++ #include <memory> int main(int argc, char* argv[]) { const auto uptr = std::make_unique<int>(250); [uptr](){ }(); return 0; } ``` this code instantly crashes clangd with signal 11. It has to be something specifically about {unique, smart}_ptrs? no crash when capturing primitives at least...

Hey, this just happened to me on: clangd --version clangd version 18.1.3 (https://github.com/llvm/llvm-project c13b7485b87909fcf739f62cfa382b55407433c0) Features: linux+grpc Platform: x86_64-unknown-linux-gnu I could boil it down to the following: ```c++ #include <memory> int main(int argc, char* argv[]) { const auto uptr = std::make_unique<int>(250); [uptr](){ }(); return 0; } ``` this code instantly crashes clangd with signal 11. It has to be something specifically about {unique, smart}_ptrs? no crash when capturing primitives at least... Debug log + stack trace: ``` [START][2024-08-28 21:29:10] LSP logging initiated [INFO][2024-08-28 21:29:10] .../vim/lsp/rpc.lua:733 "Starting RPC client" { cmd = {
