Issue description

I try to migrate table using the tool gh-ost that uses go-sql-driver/mysql but each time I get the same error unexpected error: Err: runtime error: index out of range. Do you have any idea how to fix the issue?

Thank you

There is ticket in gh-ost

Hi @palexvs

I have already fixed a similar panic here #69
But I don't know whether gh-ost has already ported it or not.

Can you use go-mysql to test your program directly? So that I can know how to fix your issue.

Thanks! I will try
