We can have different software development opinions about such a source code adjustment. Does it improve the indentation for the parameters which are passed to this function call? > and just makes the code slower (one more test in the allocation path)? Do we stumble on a target conflict for the shown implementation detail? Does the previous size calculation contain the general possibility for an integer overflow? https://cwe.mitre.org/data/definitions/190.html The value for the variable “len” (and also “n”) might be small enough so that the computed value will usually not exceed the data type limit in this use case.
