Expected behaviour
Desktop client should not use invalid memory and should have not leaks, but it have some.
Nextcloud doesn't crash, but later invalid memory usage may be cause of crashes and undefined behaviors
Steps to reproduce
- Open Nextcloud in Valgrind -
valgrind --leak-check=full --num-callers=50 nextcloudor compile it with address sanitizer support - Connect account to server
Client configuration
Client version: 3.0.1 PPA
Operating system: Ubuntu 20.04
OS language: PL
Installation path of client: Default
Server configuration
Nextcloud version: 19.0.2
