Hello,
I'm evaluating boost.process. It seams to me that it is impossible to
distinguish a normal exit from a termination by a signal (for instance
SIGBUS etc.).
child::exit_code() calls eval_exit_status() that expands on POSIX to:
if (WIFEXITED(code)) {
return  WEXITSTATUS(code);
} else if (WIFSIGNALED(code))
{

        return
WTERMSIG(code);

    }
    else

{

        return
code;

    }
