Bug #10777
closedvariable gets reset when passing a named argument to a function, if the name of this argument is the same as variable name
Description
I have a function, say function1 that has a variable, named param with a value of true.
from this function I call another function, function2 with the following call:
function2(param=false)
During this call the value of param in function1 gets changed to false, which absolutely should not happen.
Example code:
def func2(param=nil)
puts "param in func2 is #{param}"
end
def func1(param="Hello")
puts param
func2(param="Goodbye")
puts "param in func1 is #{param}"
end
func1
Hello
param in func2 is Goodbye
param in func1 is Goodbye
=> nil
The same in a pastebin:

This behavior is observed also in ruby-1.9.3-p545
