Bug #1042
closed
RDoc crashes while generating HTML after parsing a Ruby DSL.
Description
=begin
I maintain a SQL/Injection DSL written in Ruby. Recently RDoc began to crash when I would run the usual API documentation generation rake task. The source-code for this DSL, which causes RDoc to crash in the middle of generating HTML documentation, is located here: http://github.com/postmodern/ronin-sql/tree/master.
$ git clone git://github.com/postmodern/ronin-sql.git
$ cd ronin-sql
$ rake19 --trace docs # I configured Ruby 1.9.1-rc2 to with --program-suffix=19
