"--mysqld=--innodb_log_block_size=16384" is the cause.

The assert is that all AIO has to be a multiple of log block size, and there the log block size is very large and obviously not tested before. The fix would be to assert that size and offset are the multiples of the smallest possible instead of actual log block size, i.e. 512 bytes.
