Recursive function in local context

[epatrizio]

Execution: OK

function fact(n)
  if n <= 1 then
    return 1
  else
    return n * fact(n-1)
  end
end
print(fact(5)) -- 120

Execution: KO! (The only difference is that function is local)
Error message: Interpretation error: Typing error: attempt to call a non function value

local function fact(n)
  if n <= 1 then
    return 1
  else
    return n * fact(n-1)
  end
end
print(fact(5))

The problem seems to come from the scope analysis

local v2 = function (v0)
 if v0<=1 then return 1
 else return v0*v1(v0-1) end
end

local v2 instead of local v1
