mysqld crashes at start when I enable log_bin

[Serge Shakhov]

Percona mysqld 5.7.13-6 on Ubuntu 16.04.1 LTS
crashes if I try to enable log_bin option:

Hi Serge,

Could you
check datadir and binary logging related system variables:

 mysqld --help --verbose 2>&1|egrep -i 'datadir|log'

There is a stack trace, so if the issue is easy to reproduce, please obtain a core dump and provide full stack trace:

Hi Nickolay

Unfortunately it's too late, I don't use that server and database anymore so it's impossible to reproduce.
Feel free to close the case.
Thanks.
