Description of problem:
I have written a very simple sample which uses fcntl(..), the same sample works 
fine on i386 RedHat Linux system but failed on Itanium RedHat linux system.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.I created sample tfcntl.c

#include <stdio.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/file.h>
#include <sys/stat.h>
#include <fcntl.h>

int main( )
{

        int fd;
        struct flock   farg;

        farg.l_type   = F_WRLCK;
   farg.l_whence = 0;
   farg.l_start  = 0;
   farg.l_len    = 0;



        fd=open("/yourpath/tt", O_RDWR | O_CREAT, S_IRWXU | S_IRWXG | S_IRWXO);

        if (fd > 0) {
                printf("fd=%d\n",fd);

                if ((fcntl (fd, F_SETLK, & farg)) != -1)
                        printf("Locked\n");
                else
                        printf("Failed to lock\n");
        }

        return 0;
}
2.Compile: >gcc -o tf tfcntl.c
3.Run: >tf
	

Actual Results:  On IA64:
fd=3
Failed to lock

On i386 (or i686):
fd=3
Locked

Expected Results:  fd=3
Locked
