Bug #13392: TracePoint doesn't work correct with monkey patches / aliased methods
https://bugs.ruby-lang.org/issues/13392

* Author: areman01 (Andr Kullmann)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-linux]
* Backport: 2.2: UNKNOWN, 2.3: UNKNOWN, 2.4: UNKNOWN
----------------------------------------


**Command**

~~~ ruby
ruby tracepoint_bug.rb
~~~

**Output**

~~~
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.
