TracePoint doesn't work correct with monkey patches / aliased methods
ruby-2.4.1-p111 (x86_64-linux) tracepoint_bug_ext.rb:4 call to_s tracepoint_bug_ext.rb:5 c_call to_s tracepoint_bug_ext.rb:5 c_return to_s racepoint_bug.rb:12 return to_s
Why the call event on to_s is in file tracepoint_bug_ext.rb and the return event in file tracepoint_bug.rb? I think it's a bug. In jruby, for example, the call and the return event are both fired in the tracepoint_bug_ext.rb file.
