execv fails with EFAULT

[Prasanta Sadhukhan <Prasanta.Sadhukhan@Sun.COM>]

Hi,

When I tried the following program
void test4()
{
    printf("doing execv\n");
    if(execv("/bin/ls", "-l") == -1)
        printf("exec failed with errno %d\n", errno);
    else
        printf("exec succeed\n");
}

I see that execv is failing with errno 14(EFAULT).
I am using RH9 2.6 kernel. Does anybody know what is the cause?

Regards
