Here is a test case.

  (let* ((el-file (make-temp-file "test" nil ".el"))
         (elc-file (concat (file-name-sans-extension el-file) ".elc")))
    (unwind-protect
        (let ((byte-compile-warnings t))
          (with-temp-file el-file
            (dolist (form '((require 'cl-lib)
                            (put 's 'buf "abcd")
                            (cl-callf2 cl-concatenate 'string (get 's 'buf) "efg")
                            (provide 't)))
              (insert (prin1-to-string form))

      (when (file-exists-p elc-file)
        (delete-file elc-file)))))
