Although it is unclear without the backtrace by ruby itself, it seems caused by a wrong argument to Mysql2::Client#connect.
https://github.com/brianmario/mysql2/blob/785969fbceadd96d495ec9fecc67efee03d0056c/ext/mysql2/client.c#L438
That method seems to expect a Hash as 8th argument, but no check.

Thank you for the report.

Maybe https://github.com/brianmario/mysql2/issues/1075 seems related. Anyway, the issue seems to occur in mysql2 library. Cloud you ask them first?
