Sujatha 836d708997 MDEV-22451: SIGSEGV in __memmove_avx_unaligned_erms/memcpy from _my_b_write on CREATE after RESET MASTER
Analysis:
========
RESET MASTER TO # command deletes all binary log files listed in the index
file, resets the binary log index file to be empty, and creates a new binary
log with number #. When the user provided binary log number is greater than
the max allowed value '2147483647' server fails to generate a new binary log.
The RESET MASTER statement marks the binlog closure status as
'LOG_CLOSE_TO_BE_OPENED' and exits. Statements which follow RESET MASTER
try to write to binary log they find the log_state != LOG_CLOSED and
proceed to write to binary log cache and it results in crash.

Fix:
===
During MYSQL_BIN_LOG open, if generation of new binary log name fails then the
"log_state" needs to be marked as "LOG_CLOSED". With this further statements
will find binary log as closed and they will skip writing to the binary log.
