Invalid access to memory

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)>

I came back to WinSCP this morning, and a few of my sessions had expired. Instead of getting a "reconnect" on the second or third one, I got this.

WinSCP 5.6.1

Error message:
Invalid access to memory.

Thanks for your report.

Are you able to reproduce the problem?
