Description Ilya Taranov 2020-06-16 20:05:28 UTC

Application: kdevelop (5.5.1)

Qt Version: 5.13.2
Frameworks Version: 5.68.0
Operating System: Linux 5.6.11-200.fc31.x86_64 x86_64
Distribution: "Fedora release 31 (Thirty One)"

-- Information about the crash:
Create an empty CMake C++ project, add the following code (this example does not cause crash).

```
#include <iostream>
#include <thread>
#include <boost/asio.hpp>

int main(int argc, char **argv) {
    using namespace boost::asio;
    using boost::system::error_code;

    io_context ioctx;
    ip::tcp::acceptor acceptor(ioctx);

    auto f = [](error_code ec, ip::tcp::socket x) {
        std::thread([]() { });
    };

    acceptor.async_accept(f);

    return 0;
}
```

- What I was doing when the application crashed:

change:
        std::thread([]() { });
to
        std::thread([x]() { });

Kdevelop immediately crashes.

$ llvm-config --version
9.0.1

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
