When compiling some existing code on Snow Leopard, I'm getting

about the use the use of the "%p" format specifier that seem

For example
<jhr@woton> cat p.c
#include <stdio.h>
void foo (int *x) { printf("%p\n", x); }
<jhr@woton> gcc -c -pedantic -m64 p.c
p.c: In function ‘foo’:
p.c:2: warning: format ‘%p’ expects type ‘void *’, but argument 2
has type ‘int *’
Since pointer types silently convert to void * in other cases, this
warning
seems wrong to me.
FWIW I've also compiled this example using gcc 4.3 on Linux and do
not get a warning.
Is this behavior a bug or a feature?
This is not specifically known in gcc 4.2 but seems related to another
known bug. Please file a bug report and refer to bug 5935478.
