Subject: [Bug nptl/784] New: pthread_join causes a segmentation fault when it is called in catch block

I've found the pthread_join() function seems to cause a segmentation fault when
one thread throws an exception and the other thread waits for its termination 
in
its own catch block.

This is a simple source code.

#include <pthread.h>

void* thread1(void* arg) {
    try {
        /* Throw an exception and terminate this thread.*/
        throw 1;
    } catch (...) {
    }
}

int main(int argc, char* argv[]) {
    pthread_t tid = 0;
    try {
        pthread_create(&tid, NULL, thread1, 0);
        throw 1; // Throw an exception
    } catch (...) {
        /* Wait for child thread's termination in catch block. */
        if (tid)
            pthread_join(tid, NULL); // This causes segmentation fault.
    }
    return 0;
}

Here is my g++ version that compiled the source code.

gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5)
