+        make-docfile: don't corrupt heap for an invalid .elc file
+        "printf '#@1a' > in.elc; ./make-docfile in.elc" would store 0
+        one byte before just-malloc'd saved_string buffer.
+        * make-docfile.c (scan_lisp_file): Diagnose an invalid dynamic
+        doc string length.  Also fix an always-false while-loop test.
