Invalid access to memory

error message when synchronizing a large remote server directory to a local drive.
The error happened 3 times today shortly before the comparison finished (after almost 2 hours each time).
I have encountered the issue once before, but it disappeared at the next attempt

WinSCP 6.1

Error message:
Invalid access to memory.

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.

@hcarpentier: Thanks for your report. Unfortunately, it's quite likely that amount of the file in your directories reached a limit that WinSCP can handle. Consider excluding some files/folder from the synchronization, or splitting the synchronization to parts.
