      Hm, the root cause is 7.3.776 and we need to initialize now reg_buf in
      case it is not set:

      diff --git a/src/regexp.c b/src/regexp.c
      --- a/src/regexp.c
      +++ b/src/regexp.c
      @@ -4079,6 +4079,8 @@
      mch_errmsg("(\n");
      }
      #endif
      + if (reg_buf == NUL || reg_buf == NULL)
      + reg_buf = curbuf;


      regards,
      Christian
