The enclosed code hangs after printing "In parent" with *-2.96-54,
but works fine with *-2.96-60.  Since no compiler update has been
issued for Red Hat 7, I figured I should report it as a bug.

    M.E.O.

Enc.

rh7% cat buggy.cc
#include <pthread.h>
#include <iostream>

void * child_fn(void *) {
    cout << "In child" << endl;
    return 0;
}

int main() {
    cout << "In parent" << endl;
    pthread_t child_tid;
    if (pthread_create(&child_tid, 0, child_fn, 0) == 0) {
        pthread_join(child_tid, 0);
    }
}
