Ruby

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?
