[valgrind] [Bug 369209] valgrind loops and eats up all memory (very slowly) when the current working directory doesn't exist.

Hi Mark,
I get this compilation warning on Solaris:

nocwd.c: In function ‘main’:
nocwd.c:28:3: warning: missing sentinel in function call [-Wformat=]
   execlp ("echo", "echo", "Hello", "World", NULL);

And indeed, man page for execlp (Linux & Solaris) says it is supposed to be
used this way:
int execlp(const char *file, const char *arg, ...
                       /* (char  *) NULL */);

So this simple change fixes the warning:
-   execlp ("echo", "echo", "Hello", "World", NULL);
+  execlp ("echo", "echo", "Hello", "World", (char *) NULL);


As for the test itself, it cannot simulate invalid cwd on Solaris, because
rmdir returns EINVAL:
       EINVAL          The  directory  to be removed is the current directory,
                       or the final component of path is ".".

Is there any other way how to simulate invalid cwd?
