Bug #5865: Exception#== should return false if the classes differ
https://bugs.ruby-lang.org/issues/5865

Author: Hiro Asari
Status: Open
Priority: Low

Category: 
Target version: 
ruby -v: ruby 2.0.0dev (2011-12-31 trunk 34165) [x86_64-darwin11.2.0] 


Documentation says "If obj is not an Exception, returns false. Otherwise, returns true if exc and obj share same class, messages, and backtrace."

However,

$ ruby2.0 -v -e 'x=RuntimeError.new("msg"); y=ScriptError.new("msg"); p x==y'
ruby 2.0.0dev (2011-12-31 trunk 34165) [x86_64-darwin11.2.0]
true
