bug in boost.thread on freebsd 8.0

[shubin_evgeniy@…]

I use boost1.43 on FreeBSD 8.0-RELEASE-p3 amd64, installed from ports. Here is a simple program that causes an assertion:

Assertion failed: (!pthread_cond_wait(&cond,m.mutex()->native_handle())), function wait, file ./boost/thread/pthread/condition_variable.hpp, line 20.

during execution.

#include <boost/thread.hpp>
#include <cstdlib>

using namespace std;

void ThreadFun(int number)
{
    sleep(5);
}

int main(int argc, char** argv)
{
    if (argc > 1)
    {
        pid_t pid = fork();
        if (pid < 0)
        {
            return EXIT_FAILURE;
        }
        else if (pid > 0)
        {
            return EXIT_SUCCESS;
        }
    }
    boost::thread th1(boost::bind(&ThreadFun, 1));
    th1.join();
    return EXIT_SUCCESS;
}

Error occurs only when I execute program with command line arguments(when the process forks) and only on freebsd 8.0 (on ubuntu 10.04 x64 and on freebsd 7.3 amd 64 it works correct).

Boost.Thread cleanup when the program exit. Do you know if Boost.Thread can do something to attached a handler when the dlclose is called on its dl handle?

[shubin_evgeniy@…]

This bug fixes by compiling with -pthread option of gcc

[viboes]

Do you mean that the ticket can be closed or that something must be changed on the way Boost.Thread is built? If the first be free to close it yourself.
