Solidity Bug Info
ABIEncoderV2PackedStorageStorage structs and arrays with types shorter than 32 bytes can cause data corruption if encoded directly from storage using the experimental ABIEncoderV2.
|Elements of structs and arrays that are shorter than 32 bytes are not properly decoded from storage when encoded directly (i.e. not via a memory type) using ABIEncoderV2. This can cause corruption in the values themselves but can also overwrite other parts of the encoded data.|
