New comment by balejk on void-packages repository https://github.com/void-linux/void-packages/issues/37442#issuecomment-1150021297 Comment: Never mind, I didn't realize that the dependency on `spdlog` was introduced to `mtxclient` only after its latest release. Now I think the problem is connected with the recent update of `json-c++`, which also seems to be what the backtrace implies. My understanding is limited, but is it possible that the problem was caused by the `nheko` rebuild (required because of the `spdlog` update) which used the new version of `json-c++` while `mtxclient` is built with the older version?
