Does not reproduce for me:

$ cat foo.c && gcc -m64 foo.c -o foo32 && gcc foo.c -o foo64 && file
foo32 foo64 && ./foo32 && ./foo64
#include "stdio.h"
#include "stdlib.h"
main() {
	printf("1 '%.0s'\n", "foobar");
	printf("2 '%.*s'\n", 0, "foobar");
	exit(0);
}
foo32: Mach-O 64-bit executable x86_64
foo64: Mach-O executable i386
1 ''
2 ''
1 ''
2 ''

OS X 10.5.6 (Darwin 9.6.0). i686-apple-darwin9-gcc-4.0.1. Same linkage for both:

/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
version 111.1.3)
