[ruby-core:91680] [Ruby trunk Bug#15634] TracePoint seems to be skipping some methods.

[samuel]

Issue #15634 has been updated by ioquatix (Samuel Williams).


Here is more elaborate example:

```ruby
#!/usr/bin/env ruby

trace_point = TracePoint.new(:call, :return, :line, :c_call, :c_return, :b_call, :b_return) do |trace|
    puts [trace.path, trace.lineno].join(":")
end

trace_point.enable

values = {foo: 10}

def shell_escape(x)
    x
end

values.map{|key, value| [
    key.to_s.upcase,
    shell_escape(value) # TracePoint is never triggered for this line.
]}
```

Here is output:
