QPID-5473: Recovery where last record in file is truncated (ie spans files), but following file is uninitialized causes crash
> [linearstore] Recovery of journal in which last logical file contains truncated record causes crash
> ---------------------------------------------------------------------------------------------------

> Key: QPID-5473
> URL: https://issues.apache.org/jira/browse/QPID-5473
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker
> Reporter: Kim van der Riet
> Assignee: Kim van der Riet
>
> When the store recovery process encounters a journal where the last logical file is full and the last record in that file is also incomplete (ie this record would ordinarily span this journal file and the next if it were present), then the recovery process crashes with a segfault.
> There is no specific reproducer, but using large message sizes in a test will increase the probability that this error will occur, and killing the broker suddenly (ie with signal SIGKILL) increases the probability that this error will occur.
> This error could also be synthesized by deleting the last file(s) in a valid journal provided that the last record in the remaining journal files is still undequeued and spans to a deleted file.
