ERC20Votes._writeCheckpoint(ERC20Votes.Checkpoint[],function(uint256,uint256) returns(uint256),uint256) (@openzeppelin/contracts/token/ERC20/extensions/ERC20Votes.sol#236-250) uses a dangerous strict equality:
- pos > 0 && ckpts[pos - 1].fromBlock == block.number (@openzeppelin/contracts/token/ERC20/extensions/ERC20Votes.sol#245)
Don't use strict equality to determine if an account has enough Ether or tokens.

ERC20Votes._moveVotingPower(address,address,uint256).oldWeight_scope_0 (@openzeppelin/contracts/token/ERC20/extensions/ERC20Votes.sol#230) 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.

ERC20Permit.constructor(string).name (@openzeppelin/contracts/token/ERC20/extensions/draft-ERC20Permit.sol#35) shadows:

Variable 'ECDSA.tryRecover(bytes32,bytes).r (@openzeppelin/contracts/utils/cryptography/ECDSA.sol#59)' in ECDSA.tryRecover(bytes32,bytes) (@openzeppelin/contracts/utils/cryptography/ECDSA.sol#54-83) potentially used before declaration: r = mload(uint256)(signature + 0x20) (@openzeppelin/contracts/utils/cryptography/ECDSA.sol#76)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

ERC20Permit.permit(address,address,uint256,uint256,uint8,bytes32,bytes32) (@openzeppelin/contracts/token/ERC20/extensions/draft-ERC20Permit.sol#40-59) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= deadline,ERC20Permit: expired deadline) (@openzeppelin/contracts/token/ERC20/extensions/draft-ERC20Permit.sol#49)
Avoid relying on block.timestamp.
