Memory leak in logger

[chep]

I tried to download files via FTP with MAVSDK_FTP_DEBUGGING and MAVSDK_MESSAGE_DEBUGGING enabled.

The memory consumption was really big and always increased until OOM. I think there is a memory leak in Log* functions because when I disable debug, the problem is gone.

Interesting! That will be fun to track down. Thanks for the report.

Could the leak be in the FTP code? What sort of FTP action are you doing when debugging this?

I was using ftp client with burst download.
