I reproduced a parser error in eBlockerOS 4.0.3 with the [uBlock Annoyances source]( https://raw.githubusercontent.com/uBlockOrigin/uAssets/master/filters/annoyances.txt): a blank rule can match every URL. The same code is present in the current 4.1 development branch. A small fix and regression tests are prepared. Until it is released, disable the affected custom list if unrelated sites show tracking or malware warnings.
**GitHub issue:** [#465]( https://github.com/eblocker/eblocker/issues/465)
