Hello,

In TracePoint, trace on 'c_call' doesn't trace the call made to 'trace' method, where as trace on 'c_return' does, is this expected behaviour? 

Here's the code I used to reproduce it:

=== Code (c_return)
    class Car
      def self.start
        print "Started..."
      end
    end

    TracePoint.trace(:c_return) do |tp|
      puts "'#{tp.event}' event occurred in #{tp.defined_class}##{tp.method_id}"
    end

    Car.start

=== Env

Ruby 2.1.0


=== Actual output

    'c_return' event occurred in #<Class:TracePoint>#trace
    Started...'c_return' event occurred in IO#write
    'c_return' event occurred in Kernel#print

=== Expected output

    Started...'c_return' event occurred in IO#write
    'c_return' event occurred in Kernel#print

=== Code on eval.in

Here's the link to code on eval.in:

Thanks.
