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)

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.
