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

[deeedob]

Hey, this just happened to me on:

clangd --version
clangd version 18.1.3 (https://github.com/llvm/llvm-project c13b748)
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

Author: None (deeedob)

Hey, this just happened to me on:

clangd --version
clangd version 18.1.3 (https://github.com/llvm/llvm-project c13b748)
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...

Could you please try 19 or main branch?

[deeedob]

Tried on:

clangd version 20.0.0git (https://github.com/llvm/llvm-project 5b41eb3)
Features: linux+grpc
Platform: x86_64-unknown-linux-gnu

still crashes

[HighCommander4]

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]

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:

{
  "directory": "/home/ddob/Coding/clangd_lambda_capture_cash/build/debug-clang",
  "command": "/usr/bin/clang++ -Wall -Wextra -Wpedantic -Wshadow -Wnon-virtual-dtor -Wold-style-cast -Wcast-align -Wunused -Woverloaded-virtual -Wconversion -Wsign-conversion -Wmisleading-indentation -Wduplicated-cond -Wduplicated-branches -Wlogical-op -Wnull-dereference -Wuseless-cast -Wdouble-promotion -Wformat=2 --coverage -fPIC -g -O0 -std=gnu++23 -o CMakeFiles/cpp_preset.dir/main.cpp.o -c /home/ddob/Coding/clangd_lambda_capture_cash/main.cpp",
  "file": "/home/ddob/Coding/clangd_lambda_capture_cash/main.cpp",
  "output": "CMakeFiles/cpp_preset.dir/main.cpp.o"
}

[HighCommander4]

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 c13b748)
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...
