Crash in purge_sys_t::iterator::free_history_rseg()

    XMLWordPrintable

Details

    Description

      The recently extended test innodb.log_file_size_online,encrypted occasionally triggers a crash of InnoDB when built WITH_ASAN=ON or WITH_MSAN=ON. I can reproduce it in combination with CMAKE_BUILD_TYPE=RelWithDebInfo; on https://buildbot.mariadb.org I have seen it fail with CMAKE_BUILD_TYPE=Debug as well. The problem appears to be that the rseg.undo_cached list is empty.
