$ cat ptr.c
#include <stdio.h>
struct a {
char b[100];
int a;

int main(int argc, char *argv[])
{
struct a *a = NULL;
void *ptr;
if (&a->b)
puts("ok, not null #1");
if (&a->b == NULL)
puts("ok, null ? #1");
ptr = &a->b;
if (ptr)

if (ptr == NULL)
puts("ok, null ? #2");

}
$ gcc ptr.c -o ptr
$ ./ptr
ok, not null #1
ok, null ? #1
ok, null ? #2
The same results with gcc 4.4.3, gcc 4.5.0 (ubuntu gcc-snapshot package).
Did not try gcc 3.x series.
$ clang ptr.c -o clang-ptr
$ ./clang-ptr
ok, null ? #1
ok, null ? #2

------- Comment #2 from zilvinas dot valinskas at gmail dot com 2010-06-16 10:29 -------
I don't agree. This is an optimizer bug ("dead code elimination" don't know
much of GCC). Consider that there is a function like this:
$ cat ptr.h
struct a {
char b[100];
int a;
};
$ cat ptr.c
$ cat ptr.c
#include <stdio.h>
#include "ptr.h"
int main(int argc, char *argv[])
{
struct a *a = NULL;
function(a);
return 0;
}
$ cat func.c
#include <stdio.h>
#include "ptr.h"
void function(struct a *a)
{
void *ptr;
if (&a->b)
puts("ok, not null #1");
if (&a->b == NULL)
puts("ok, null ? #1");
ptr = &a->b;
if (ptr)
puts("ok, not null #2");
if (ptr == NULL)
puts("ok, null ? #2");
}
$ gcc ptr.c func.c -o ptr
$ ./ptr
$ ./ptr
ok, not null #1
ok, null ? #1
ok, null ? #2
Still the same problem (maybe not a problem). But how does GCC is able to tell
that in this particular case func() is invoked with a NULL pointer as parameter
(not valid pointer) and eliminates code just like that ???
Mind you this code is an approximation of bug I was tracking not so long time
ago.

I'd argue it's a QOI issue that the C frontend via
c_objc_common_truthvalue_conversion should not convert
if (&a->b)
to
if (0)
if the offset of b is zero.
