Description
For some, even small, tables (with .ibd files passed through normal recovery and shutdown) innochecksum from MariaDB versions 10.1,.x and 10.2.x dumps core because of floating point exception, like this:

If we let it create core file, gdb shows the following:

innochecksum from MySQL 5.6 or Percona Serrver 5.7.14 works without dumping core on the same .ibd file:
