Latest crash information logs sent via email.

Thanks for your feedback. I'm sending you a new debug build.

Still occurs, attached is the latest log.

Thanks for the new test build, testing has begun.

This bug has been added to the tracker:
https://winscp.net/tracker/1606

I'm sending you an email with a development version of WinSCP.

I also experienced the "invalid access to memory" WinSCP ver 576 on Windows 10.
It gave me some type of timeout error while I was deleting a directory on the left side user panel.

Can you reproduce the problem with the latest version of WinSCP? If you can please, post a separate report as this seems unrelated.

Thanks. Will contact you in few days.

Using DotNet 4.7.1 on X64 platform with WinSCP 5.12.1-beta during PutFiles to an OpenSSH 7.6 (SFTP) host it crashes quite often (see attached log).

This usually happens if there is a delay between files.

I also experienced the "invalid access to memory" WinSCP ver 576 on Windows 10.
It gave me some type of timeout error while I was deleting a directory on the left side user panel. Then this error:
Stack trace:

(001DBDB4) Vcl::Forms::TCustomForm::UpdateActions
I had to shut WinSCP down via Task Manager as the error window was in loop I could not break out of.

Managed to reproduce it, took some time reproduce it, hope the attached file helps.

So far haven't been able to reproduce the problems with the new build (but I have been on vacation the past week so not much testing was done).

Will report in a few days

Got another message: "Assertion failed: FPendingActions->Count == 0, file core\SessionInfo.cpp, line 1438", doesn't seem to be related to this bug though.

1) Were you able to reproduce the original problem with the new build?

2) Please send a log for the new problem too.

Got another message: "Assertion failed: FPendingActions->Count == 0, file core\SessionInfo.cpp, line 1438", doesn't seem to be related to this bug though.

Finally got one, sending it via mail after compression (it's quite large).

-Edit- Sent it via wetransfer, your mailserver wouldn't accept the filesize.

Thanks, have been testing it but cannot seem to crash it again (with the mentioned build it used to be a 70% crash rate), could it be that this one contains some additional patches?

Not really.
So can you at least post a session log file from the official version (when it crashes)?
