ERC20Votes._writeCheckpoint(ERC20Votes.Checkpoint[],function(uint256,uint256) returns(uint256),uint256) (@openzeppelin/contracts/token/ERC20/extensions/ERC20Votes.sol#237-251) uses a dangerous strict equality:
- pos > 0 && ckpts[pos - 1].fromBlock == block.number (@openzeppelin/contracts/token/ERC20/extensions/ERC20Votes.sol#246)
Don't use strict equality to determine if an account has enough Ether or tokens.

ERC20Votes._moveVotingPower(address,address,uint256).newWeight_scope_1 (@openzeppelin/contracts/token/ERC20/extensions/ERC20Votes.sol#231) is a local variable never initialized
ERC20Votes._moveVotingPower(address,address,uint256).oldWeight_scope_0 (@openzeppelin/contracts/token/ERC20/extensions/ERC20Votes.sol#231) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.
