"name": "DynamicConstructorArgumentsClippedABIV2",
"summary": "A contract's constructor that takes structs or arrays that contain dynamically-sized arrays reverts or decodes to invalid data.",
"description": "During construction of a contract, constructor parameters are copied from the code section to memory for decoding. The amount of bytes to copy was calculated incorrectly in case all parameters are statically-sized but contain dynamically-sized arrays as struct members or inner arrays. Such types are only available if ABIEncoderV2 is activated.",
"introduced": "0.4.16",
"fixed": "0.5.9",
"severity": "very low",
"conditions": {
"ABIEncoderV2": true
}

"name": "UninitializedFunctionPointerInConstructor",
"summary": "Calling uninitialized internal function pointers created in the constructor does not always revert and can cause unexpected behaviour.",
