How to reproduce:
class A
def x
yield
ensure
y
end
def y
end
end
# Work
A.new.x do
end
# Not work
# trace:
# [2] /tmp/a.rb:5:in A.x
# [0] /tmp/a.rb:15
# /tmp/a.rb:5: undefined method 'y' for main (NoMethodError)
A.new.x do
break
end
# trace:
# [2] /tmp/a.rb:5:in A.call
# [0] /tmp/a.rb:19
# /tmp/a.rb:5: undefined method 'y' for main (NoMethodError)
lambda do
A.new.x do
return
end
end.call
`self` in ensure is broken when yield and break/return are used.
