Part of the pages of the second level blobs is not released when deleting
relations.

Key: CORE-5618
URL: http://tracker.firebirdsql.org/browse/CORE-5618
Project: Firebird Core
Issue Type: Bug
Components: Engine
Affects Versions: 3.0.2
Reporter: Denis Logashov
Problem in the function "delete_tail" in the block where the pages of blobs of
the second level are released. When you get the end of data containing page
numbers of second-level blobs, you do not need to subtract the header size,
otherwise 7 pages remain occupied.
const ULONG * const end2 = page2 + ((bpage-> blp_length - BLP_SIZE) / sizeof
(ULONG));
If I'm right I prepare a pull request.
