Hello. This is a patch for Bug #14702, which I don't think is fully addressed.
The tests in the patch should fail on both trunk and ruby_2_5.

    Fix TracePoint for nested iseq loaded from binary [Bug #14702]

    When loading iseq from binary while a TracePoint is on, we need to
    recompile instructions to their "trace_" variant. Before this commit
    we only recompiled instructions in the top level iseq, which meant
    that TracePoint was malfunctioning for code inside module/class/method
    definitions.

    * compile.c: Move rb_iseq_init_trace to rb_ibf_load_iseq_complete.
      It is called on all iseqs during loading.

    * test_iseq.rb: Test that tracepoints fire within children iseq when
      using load_from_binary.

I'll set Backport field for 2.5 as REQUIRED since https://bugs.ruby-lang.org/issues/15717 claims the issue was not fixed on ruby_2_5.
