-Subject: [PATCH 3/3] Fix Data Corruption Bug when Streaming with an Attached
- Dict in HC Mode
-
-This diff fixes an issue in which we failed to clear the `dictCtx` in HC
-compression. The `dictCtx` is not supposed to be used when an `extDict` is
-present: matches found in the `dictCtx` do not account for the presence of an
-`extDict` segment, and their offsets are therefore miscalculated when one is
-present. This can lead to data corruption.
-
-This diff clears the `dictCtx` whenever setting an `extDict`.
-
-This issue was uncovered by @terrelln's fuzzing work.
