Description
Hi, boost interprocess anonymous mutex seems not to be handling well in ARM64 of Apple Silicon.
```C++
#include
#include
#include
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("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**
```bash
clang++ -std=c++17 -arch arm64 boost_interprocess.cpp -I -o boost_interprocess_arm64 # For arm64 only build
clang++ -std=c++17 -arch x86_64 boost_interprocess.cpp -I -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)
