Added a changelog entry for 5.6.14, 5.7.2: As commented in "log0log.h", "old_lsn" and "old_buf_free" should only be compiled when "UNIV_LOG_DEBUG" is enabled. Thank you for the bug report.
Description: as commented in log0log.h, both old_buf_free and old_lsn should only be used in the debug version. ulint old_buf_free; /*!< value of buf free when log was last time opened; only in the debug version */ ib_uint64_t old_lsn; /*!< value of lsn when log was last time opened; only in the debug version */ I think the code quoted above can be compiled only when UNIV_LOG_DEBUG is enabled. forgive my picky.... How to repeat: read the code Suggested fix: +#ifdef UNIV_LOG_DEBUG ulint old_buf_free; /*!< value of buf free when log was last time opened; only in the debug version */ ib_uint64_t old_lsn; /*!< value of lsn when log was last time opened; only in the debug version */ +#endif
