I am facing a problem in using boost::recursive_mutex.

Flow of my program is:-

1. Get a boost::recursive_mutex lock
2. Fork the process
3. In parent sleep for few seconds and then unlock boost::recursive_mutex.
4. In child call exit(0)

What is happening is that child process is calling the destructor of boost::recursive_mutex and core is dumped. I want that child process should not inherit the boost mutex lock of parent.
Please tell me how to do it.

Please find attached the core, binary file and the source files.


Stack of core dumped
