PastaToken._writeCheckpoint(address,uint32,uint256,uint256) (#1089-1107) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1099)
MasterChef.updatePool(uint256) (#1263-1279) uses a dangerous strict equality:
- lpSupply == 0 || pool.allocPoint == 0 (#1269)
