I get

[geoffk@thief geoffk]$ cat > tA2.c
#include <stdio.h>
#include <dlfcn.h>
extern void foo(void) __attribute__((weak));

int main(void)
{
   void (*foop) (void) = foo;
   asm volatile ("" : "=r" (foop) : "0" (foop));
   printf ("%p\n", foop);
   if (foop)
         foop();
     return 0;
}
[geoffk@thief geoffk]$ gcc tA2.c -o tA2
[geoffk@thief geoffk]$ ./tA2
(nil)
[geoffk@thief geoffk]$ LD_PRELOAD=./tB.so ./tA2
(nil)

on x86-linux.
