gunzip this file (it's a c header file base64 encoded from googlesource.com) to Looper.h and load it with 28.2 emacs -Q and it'll infinite loop pegging one core.  

Expected behavior:  load the file, and let me base64-decode it.

It's a long line, but not _that_ long.

If you don't want my gz file, this url will get you the same file:
