Bug #17622: Segfault in new Rails app
https://bugs.ruby-lang.org/issues/17622
* Author: peterzhu2118 (Peter Zhu)
* Status: Open
* Priority: Normal
* Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN
----------------------------------------
There is a segfault in Ruby master and Ruby 3.0.0, but not present in Ruby 2.7.2. A bisect shows that it's present since commit [a53e2850c572135ed657144bc14e47b29c64fa94](https://github.com/ruby/ruby/commit/a53e2850c572135ed657144bc14e47b29c64fa94).
# Reproduction
1. Use Ruby 3.0.0 or Ruby master.
2. Create a new Rails app (`rails new repro`).
3. Add the following `script.rb`:
```ruby
def load_rails
tp = TracePoint.new(:c_return) do
end
require './config/application'
rails = Object.const_get(:Rails)
rails.application.require_environment!
rails.application.eager_load!
end
def foo
-> do
load_rails
end
end
foo.call
puts "ok"
```
4. Run the script with `DISABLE_BOOTSNAP=1 ruby script.rb`
# Expected output
The script should print `ok`.
# Actual output
Crashes with a segfault (check file `crash.log` for full crash log).
