12.11.0.6 Access violation at address 00000000046A8D60

I got following error, while running simple select like

select min(report_date), max(report_date) from mytable.

It seems more and more frequent error in last few releases. It’s not bound to particular object though, because opening a new instance of Toad and rerunning the same statement is not giving the same error
