The ARM board is running linux-2.2.16 w/ glibc-2.1.3. The arm-linux-gcc 
version is 2.95.2.

I am using the following small test program:

#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>

void* thread (void* parm)
{
        int iteration = (int) parm;
        while (iteration)
        {
                fprintf (stderr, "GDBTEST: thread loop: %d\n", iteration--);
                sleep (1);
        }
        return (void*) 1234;
}

int main(int argc, char **argv)
{
        pthread_t tid;
        int thread_rc;

        fprintf (stderr, "GDBTEST: calling pthread_create\n");
        pthread_create (&tid, NULL, thread, ((void*) 10));
        fprintf (stderr, "GDBTEST: returned from pthread_create\n");
        fflush (stderr);

        fprintf (stderr, "GDBTEST: calling pthread_join\n");
        pthread_join (tid,(void**) &thread_rc);
        fprintf (stderr, "GDBTEST: returned from pthread_join = %d\n", 
thread_rc);

        return 0;
}

Attached are two log files: gdb.log and gdbserver.log. In gdbserver.log I have 
inserted the commands entered on the host gdb (marked by #host#).

Thanks for your help.
