Bug #14702
Updated by makoto_tajitsu@hotmail.co.jp (Makoto Tajitsu) over 7 years ago
On Ruby 2.5.1, when loading file with RubyVM::InstructionSequence.load_from_binary, TracePoint callback event is not working on loaded file.
## Steps to reproduce
Ruby version.
```
$ ruby -v
# => ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-darwin16]
```
The example with `yomikomu` gem which is simply used `load_iseq` and `load_from_binary` method to load file quickly is following.
```
$ YOMIKOMU_AUTO_COMPILE=true bundle exec irb
> TracePoint.trace(:line) { |tp| puts tp.lineno if tp.path == '/path/to/somefile.rb' }
# => #<TracePoint:enabled>
> load '/path/to/somefile.rb'
# 3
# 4
# ...
require 'yomikomu'
load '/path/to/somefile.rb' './somefile.rb'
# no tracepoint callback for line event
```
On Ruby 2.4.3, this example is working correctly, so tracepoint callback is called and output lineno to stdout when loaded file after `require 'yomikomu'`.
