ruby -v: ruby 2.1.0dev (2013-12-20 trunk 44301) [x86_64-linux]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN, 2.1: UNKNOWN


Exception message of Errno::ENOENT exception contains strings "@ rb_sysopen" or "@ dir_initialize" in Ruby 2.1.0-rc1. It doesn't contain them in Ruby 2.0. I would expect exception message not to contain those strings.

Example in Ruby 2.1:
$ irb    
2.1.0dev :001 > File.new('/path/to/not/existent/file')
Errno::ENOENT: No such file or directory @ rb_sysopen - /path/to/not/existent/file
	from (irb):1:in `initialize'
	from (irb):1:in `new'
	from (irb):1
	from /home/andrey/.rvm/rubies/ruby-2.1.0-rc1/bin/irb:11:in `<main>'
2.1.0dev :002 > Dir.open('/path/to/not/existent/folder')
Errno::ENOENT: No such file or directory @ dir_initialize - /path/to/not/existent/folder
	from (irb):2:in `open'
	from (irb):2
	from /home/andrey/.rvm/rubies/ruby-2.1.0-rc1/bin/irb:11:in `<main>'
2.1.0dev :003 >
