I cannot reproduce it.

$ cat foo.c
#include <string.h>
#include <stdio.h>

int main() {
   char *find = strstr ("**AB** **CD** **AB** **CD** **CD**", "**CD**");
   printf("%s\n", find);
   return 0;
}
$ gcc -Wall -O2 foo.c lib/strstr.c -I..
$ ./a.out
**CD** **AB** **CD** **CD**

Can you please give more details
  1) about your platform (CPU, 32-bit or 64-bit), gcc version, compilation
     flags,
  2) Show the stack trace that you get when you compile with -g and without
     optimization and then run gdb:
     $ gdb a.out
     (gdb) run
     (gdb) where
