It’s usually some method called on a very large negative Fixnum. Note  
below how different install runs produce different errors. (Who said  
that computers were deterministic?)

Installing ri documentation for facets-1.7.46…

RDoc failure in lib/facets/more/cookie.rb at or around line 336 column  
-517618807

Before reporting this, could you check that the file  
you’re documenting compiles cleanly–RDoc is not a  
full Ruby parser, and gets confused easily if fed  
invalid programs.

The internal error was:
