Issue #8565 has been updated by charliesome (Charlie Somerville).
I took a quick look at why this is happening. The equality fails because the source of the two regexps is different:
1.9.3:
>> Regexp.new('\/').source
=> "\\/"
>> /\//.source
=> "\\/"
2.0.0:
>> Regexp.new('\/').source
=> "\\/"
>> /\//.source
=> "/"

Issue #8565 has been updated by cedric.brancourt (Cedric Brancourt).
Hopefully this is not a bug (or I think it is not).
When you create new regexp with :
%r"\/" and Regexp.new("\/") your quote are the delimiters
when you create regexp with slashes /\// the slashes (/) are your delimiters. Your regexp should end at the second / but fortunately you can escape this one with a backslash.
So your backslash is there used to escape the second one. This mean that your regexp /\// is equal to %r"/"
[6] pry(main)> /\// == %r"/"
=> true
