panic when attempting to open symlink with O_CREAT | O_NOFOLLOW

[phcoder]

Testcase:

#include <sys/types.h>
#include <sys/stat.h>
# include <unistd.h>
#include <fcntl.h>

int
main ()
{
  int fd;

  static char const sym[] = "conftest.sym";
  symlink ("/dev/null", sym);
  fd = open (sym, O_WRONLY | O_NOFOLLOW | O_CREAT, 0);
  close (fd);
     
  unlink (sym);

  return 0;
}
