Subject: Trace API bug

Hi Everyone,

I've noticed a small bug while playing with my ruby-debug extension. I
think the current Ruby interpreter misses a 'call' event when calling
a method defined with Module#define_method. Below is the small script
that proves it:

$ cat -n t.rb
     1  class A
     2    def m1
     3      "m1 called\n"
     4    end
     5    define_method("m2") do
     6      "m2 called\n"
     7    end
     8  end
     9
    10  a = A.new
    11  set_trace_func proc {|event, file, line, *args| puts "#{event}:#{line}"}
    12
    13  a.m1
    14  a.m2
    15
$ ruby t.rb
line:13
call:2
line:3
return:4
line:14
line:6

Notice how the invocation of A#m2 doesn't emit any 'call' or 'c-call' events.
