[Bug server/10809] New: GDBServer does not post "new thread"

["a dot kattwinkel at precitec-optronik dot de" <sourceware-bugzilla at sourceware dot org>]

When locally debugging an application that creates a pthread, gdb will post a
"new thread" message when I step over the pthread_create function. However, this
does happen when I debug the identical executable using gdbserver (even
locally). The problem about this arises when I use eclipse/cdt/dsf for debugging
because normally (in the local case) this post appears to trigger an update to
the stack view so that I can control new threads from there. This does not take
place with gdbserver.

#include <iostream>
#include <pthread.h>

using namespace std;

void * ThreadProc(void * _pIn)
{
        static int a = 0;

        while (1)
        {
                cout << "Thread: " << a++;
                usleep(500000);
        }
}

int main()
{
        pthread_t hThread = 0;
        pthread_create(&hThread, NULL, ThreadProc, NULL);
        cout << "!!!Hello World!!!" << endl; // prints !!!Hello World!!!
        cout << "!!!Hello World!!!" << endl; // prints !!!Hello World!!!
        return 0;
}


Building the target
===================

g++ -ggdb -lpthread -o Test Test.cpp
