Dag-Erling Smørgrav 621f45532c tail: Fix heap overflow in -F case. ... The number of events we track can vary over time, but we only allocate enough space for the exact number of events we are tracking when we first begin, resulting in a trivially reproducable heap overflow. Fix this by allocating enough space for the greatest possible number of events (two per file) and clean up the code a bit. Also add a test case which triggers the aforementioned heap overflow, although we don't currently have a way to detect it. MFC after: 1 week Sponsored by: Klara, Inc.
