Description:
The failure was noticed in mtr's log

main.rpl_sync_binlog_basic_64  [ fail ]
ERROR: Failed to start slave mysqld 0
...
Saving core.15912

The core traces back:
#1  0x000000000067276e in handle_segfault (sig=6) at mysqld.cc:2626
#2  <signal handler called>
#3  0x00002b0648bbdfed in raise () from /lib64/libpthread.so.0

#8  0x00002b0648bb7193 in start_thread () from /lib64/libpthread.so.0

to lead to the assert on the synopsis line.

possibly the following (the error log from slave claiming on a core):

and explore logs, particularly from the slave server.

This is a duplicate of Bug#36367.  The fix was pushed May 9,2008, but it is possible that this fix did not reach the main tree until this week.  Anyway, the current code no longer has that assertion.
