// This file is a part of AddressSanitizer, an address sanity checker.

//
|
|
// Compute the level of scariness of the error message.
|
|
// Don't expect any deep science here, just a set of heuristics that suggest
|
|
// that e.g. 1-byte-read-global-buffer-overflow is less scary than
|
|
// 8-byte-write-stack-use-after-return.
|
|
//
|
|
// Every error report has one or more features, such as memory access size,
|
|
// type (read or write), type of accessed memory (e.g. free-d heap, or a global
|
|
// redzone), etc. Every such feature has an int score and a string description.
|
|
// The overall score is the sum of all feature scores and the description
|
|
// is a concatenation of feature descriptions.
|
|
// Examples:
|
|
// 17 (4-byte-read-heap-buffer-overflow)
|
|
// 65 (multi-byte-write-stack-use-after-return)
|
|
// 10 (null-deref)
