Roll back fix for github issue #350 About Scratch Usage: For compile time, scratch space is strongly recommended to be allocated immediately after database generation. For runtime, besides using scratch for corresponding database, Hyperscan also allows user to use larger scratch space allocated for another database. When multiple concurrent threads need to use the same databases and a new scratch space is required, cloning the largest one is always safe. This is realized based on API hs_scratch_size() and hs_clone_scratch(). Behaviors beyond above are discouraged and results are undefined.
