Invalid Access to Memory error on scripted 'Get'

I'm converting some MS FTP transfers in DOS batch files to Winscp.com using scripts. Several have run successfully, but today (new script) I get an "Invalid Access to Memory" error when script does a Get command. Destination folder is AS400 file system which only allows 8.3 names, if that is pertinent. File on site is 7.3 name

I have tested using get to local server file system, so AS400 file system is not issue. I can put files, list files, delete files, get a 3 byte file, but get error on 102 byte file and original larger 100KB file. This is a production server, so can't reboot during day; will try that this evening.

What version of WinSCP are you using? Can you post a log file?

Started with 4.05, now on 4.06. Also fails on another machine still on 4.05. Can copy file in GUI, not in Batch. Have tried Binary and ASCII transfer. (Identifying data obscured)

Invalid access to memory

Another user with Invalid Access to Memory problem downgraded version to 4.05 to fix/bypass problem. As it has occured for me with 4.05, I have downgraded to 4.04, and still get error on Get command. I will try to go up to 4.10

I'll send you a debug version soon.

I found my Corp. email filter put your message of 4/11 in dumpster, as it was foreign domain, and then removed it. :cry: Can you resend message, and I will watch closely to retrieve it. I'll also look for your email address in profile, and send you a message with a personal email address.

I have sent an email to the other address.

This (or at least similar) issue has been added to tracker.

We were getting 'invalid access to memory' errors when downloading filenames with 54-character names and running WinSCP 4.0.6 on our server. The error did not occur using WinSCP 4.1.9 on a PC. We upgraded the version on the server and the error no longer occurred on the server.
