"summary": "Calls to public library functions (internal functions are safe) that return nested arrays return only zeroes.",
"description": "The compiler does not complain about public library functions (internal functions are safe) returning nested arrays, but it also does not return it correctly. Thus, the function caller receives only zeroes.",
"introduced": "0.4.11",
"name": "NestedArrayFunctionCallDecoder",
"summary": "Calling functions that return multi-dimensional fixed-size arrays can result in memory corruption.",
"description": "If Solidity code calls a function that returns a multi-dimensional fixed-size array, array elements are incorrectly interpreted as memory pointers and thus can cause memory corruption if the return values are accessed. Calling functions with multi-dimensional fixed-size arrays is unaffected as is returning fixed-size arrays from function calls. The regular expression only checks if such functions are present, not if they are called, which is required for the contract to be affected.",
