Sftp plugin crash, silent, no debug messages

[MauriceSnell]

I have had repeated but intermittent crashing of TC V8.51a 64-bit during background SFTP transfers - usually uploads from my PC to a remote SFTP server.

I am using what I think is the latest plugin, V1.4.1, dated 4.3.2013.

Is there a way to enable more verbose debug? Currently the program just disappears, with no message box or debug output or windows event message that I can find.

I don't have a set way to reproduce this, but it has happened a number of times now.

Previously I was using curl-7.34.0-devel-mingw64.7z.

I have today updated to curl-7.40.0-devel-mingw64.7z and curl-7.40.0-devel-mingw32.zip.

So far, the 32-bit version has done hours of sftp uploads with no problems, however the 64-bit version has failed again. So this would appear to be an issue only with the 64-bit version.

If you haven't done so already, you should enable FTP logging in menu Configuration - Options - FTP. This also logs all plugins.

I now have a tcftp.log file covering a crash, however I can't see anything useful in there. Is there somewhere I can post it that isn't public for you to review?

Please send it to support at ghisler dot com.

Any news on this? I have the same problem. Usually at the very first file I try to upload, Total Commander crashes.

I've enabled FTP logging, but there's not much there. Here's an anonymized version of the log:

TC version is 8.52a 64-bit.

Public key or password auth doesn't make a difference.

No, unfortunately not - there is nothing in the log which would explain the crash, and I cannot reproduce it either. I can connect to Centos (ghisler.com) and Raspbian (Raspberry PI) here without problems...
