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?

I've sent you an up to date debug build.

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.

I know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.

Thanks for your report.

Running in Windows 10 virtual machine on ESXi 6.7. Using FortiClient 5.6.6 to connect to work network. Only change was enabling keep-alive (null packets at 120-300 second intervals, depending on server). Left WinSCP connections up and locked computer after ending shift. VPN connection dropped overnight, but do not know if memory error happened at same time. I believe I only had text files on remote systems open at the time.

Posting this because the program asked me to. WinSCP had been running in the background for several hours, idling (As it usually does), and when I went to switch to this, I saw this error. The last thing I did was delete a zip file from an SFTP server, yesterday.
