Interprocess anonymous mutex hangs with Apple Silicon #176

Open

Description

@r0ck3r008

Hi, boost interprocess anonymous mutex seems not to be handling well in ARM64 of Apple Silicon.

#include <iostream>
#include <boost/interprocess/managed_shared_memory.hpp>
#include <boost/interprocess/sync/interprocess_mutex.hpp>

using namespace boost::interprocess;

int main() {
    try{
        managed_shared_memory managed_shm{open_or_create, "shm", 1024};
        interprocess_mutex *mtx =
            managed_shm.find_or_construct<interprocess_mutex>("mtx")();

        mtx->lock();
        std::cout << "Critial section" << std::endl;
        mtx->unlock();
    } catch (const boost::interprocess::interprocess_exception &e) {
        std::cerr << "Interprocess exception thrown: " << e.what() << std::endl;
        _exit(1);
    }
}

Compilation steps followed

clang++ -std=c++17 -arch arm64 boost_interprocess.cpp -I<BOOST_HOME> -o boost_interprocess_arm64 # For arm64 only build
clang++ -std=c++17 -arch x86_64 boost_interprocess.cpp -I<BOOST_HOME> -o boost_interprocess_x64 # For x64 only build 

Expected Behavior
Both the instantiations should work and print Critical Section.

What was observed
When arm64 build is executed first, it works fine, but when x64 build is executed, the subsequent arm64 execution hangs.

Steps to reproduce

  • rm /tmp/boost_interprocess/shm
  • ./boost_interprocess_x64
  • ./boost_interprocess_arm64

Environment tested on

  • MacBook Air (M1, 2020)
  • MacOS Monterey 12.3.1
  • Apple clang version 13.1.6 (clang-1316.0.21.2.5)

    I don't have access to a Mac, so I would need some debugging and help from your side.
