To: Martin
I'm starting to return to development, and upgraded to the latest WinSCP.
This appears to be pretty much the same error that I saw in Feb-March.
Do you want logs, or would you like me to try a debug version of WinSCP?

P.S. This was the problem that occurs when I turn off networking overnight, while WinSCP is still running. I'd estimate the crash as 50% of the nights where I do this.
