Description

There is a commit that claims to backport #15270, ruby_2_5@66225 / aba207b7620d963e212e4187213db7e1eee7a790.
However, the patch in #15270 wasn't actually backported. For reference, here is a script that outputs

"2.6.2"
3
4
"class 1"
"class 2"

On Ruby 2.6.2, but only outputs

"2.5.5"

on Ruby 2.5.5.

p RUBY_VERSION
iseq = RubyVM::InstructionSequence.compile(<<-RUBY)
  class A
    class B
    end
  end
RUBY

iseq_bin = iseq.to_binary
TracePoint.new(:end){|tp|
  p tp.lineno
}.enable{
  RubyVM::InstructionSequence.load_from_binary(iseq_bin).eval
}

TracePoint.new(:class){|tp|
  p "class #{tp.lineno}"
}.enable{
  RubyVM::InstructionSequence.load_from_binary(iseq_bin).eval
}

If it helps, can we also backport the tests in the patch in #15270?
