Thanks for the report. Will look into it. Meanwhile, please stop using the log window.

Invalid access to memory - TLogForm::LogMemoChange

Set logging from Normal to Debug 1: worked.
Then set logging from Debug 1 to Debug 2: worked, but WinSCP Windows did not respond to input any more, logging window kept scrolling (lot of) information until the memory error happened.

WinSCP 5.7.7

Error message:
Invalid access to memory.

related crash?

WinSCP now becomes unresponsive as soon as I enable the log window (full or 500 last). Log window stays empty (gray) and I have to force WinSCP to quit (unresponsive).

logging crash

Set log file to overwrite: didn't help.
Deleted %temp% and started log window before transfers started. Worked, but as soon as transfer stalled WinSCP stalled (full CPU load on one core) and then crashed after 1-2 minutes.

logging crash

I suspect that the logging window cannot handle the sheer amount of information. I am transferring 350000 files in total and after the crash I restart the transfer with "New and Updated only" option to catch up where the crash stopped.

Re: logging crash

Thanks for your report. Actually the log window has been removed in the latest release 5.8.4. That kid of resolves this problem.
