What's your issue about?

Using the keyword argument bound for ranges on the form range(N, M) and range(x, x + N) is not syntactically forbidden. The generated bytecode of the following examples is identical to the one that would have been generated without having the bound keyword.

@external
def bar():
    for i in range(1,2,bound=2):
        pass

@external
def bar():
    x:uint256 = 1
    for i in range(x,x+1,bound=2):
        pass

How can it be fixed?

Only allow ranges on the form range(N) to have kwargs.
