It is now happening regularly.
I had problems with WinSCP having to reconnect every hour or so and dropping the session password ever since the upgrade to 5.9 but without logging the attendant error codes.
If we don't figure this out, I will have to roll back to the previous version.

The problem happened while rebooting the target WinSCP was connected to. This rebooting happens quite frequently, but only this time the Invalid memory access was reported.

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.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.

When I disconnect the VPN, then reconnecting, it happend.

The problem happens rarely. I cannot reproduce it.

Hard to reproduce, I just waked up laptop, and hit reconnect (the WinSCP was ran yesterday evening and left running in order to copy large files from remote server to local disk ) Connection to remote ssh server was established over OpenVPN. VPN disconnects when laptop goes into sleep mode after inactivity. Therefore today morning VPN was not connected (and I forgot to connect VPN before hitting reconnect). Looking at comments below I think this is due network interface which goes down during scp session and some sites became unreachable.


Good luck with patching this :-)

The problem happens rarely. I cannot reproduce it.

I had an open SFTP connection and forgot to close it when I closed my laptop and went home from work. When I opened the lid a few hours later I got this crash. I've made this mistake once or twice before without a crash so it's not 100% reproducible. Thanks for having an awesome product, this just reminds me to donate and stop being a freeloader.

Same steps as reported by: dave.methvin@...

System was sitting idle with a connection and eventually it went to sleep. This message popped up when I woke up the system a few hours later. Reconnect worked.

I will try to reproduce this.
