 This time you have caught the exception

 Try with this

pigeon% cat b.rb
#!/usr/bin/ruby
begin
  $stderr.reopen File.open 'stderr', 'w'
  $stderr.sync = true
  1/0
ensure
  $stderr.flush
  puts IO.readlines 'stderr'
end
pigeon% 

pigeon% b.rb
pigeon% 

pigeon% cat stderr
./b.rb:5:in `/': divided by 0 (ZeroDivisionError)
        from ./b.rb:5
pigeon%
