Invalid access to memory - Customdriveview::TCustomDriveView::IterateSubTree

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)>
<If relevant, consider attaching a session log file or a screenshot)>

Not sure what happened. I have been allowing the computer to go to sleep a lot while my session is open, and I just happened to come back to WinSCP and this message was up. Sorry I don't have better details.

WinSCP 5.7.3

Error message:
Invalid access to memory.

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

Used the debug version, which crashed after 1-2 hours and windows (8.1) told me sth like 'the program has stopped working, click here to terminate'

Attaching the trace log.

I assume this is not the same problem as the 'invalid access to memory'

Invalid access to memory - Customdriveview::TCustomDriveView::IterateSubTree

This error message "Invalid access to memory" showed up immediately after I finished installing the upgraded version of WinSCP on 8/15/2016. When I finished installation, I unchecked the view upgrade details page and made sure Run WinScp box was checked. Then i clicked finish. I'm running Windows 10 with the anniversary update freshly installed. I had to manually close SettingsSyncHost in order to make the installation work.

Invalid access to memory - Customdriveview::TCustomDriveView::IterateSubTree

I think this occurred following putting the computer into hibernation when I had to quickly vacate an office and move elsewhere. I only realised that there was a problem when the error screen appeared! I haven't experienced this problem under similar conditions before (I don't think).
Sorry I can't be of more help!

Invalid access to memory - Customdriveview::TCustomDriveView::IterateSubTree

Was connected at home over VNC last night. Came into work this morning and was working for some time before trying to use WinSCP. WinSCP login window was up. Entered my password, but as usually happens when I don't address the login window at first network connect, it failed the login. Entered my password a second time and it crashed.
