Description

The string that is added as the parameter for WMessageResource::resolvePluralKey, is evaluated by a grammar written with Boost spirit.
This lead to an issue noticed by OSS-Fuzz. While this is not a reasonable attack vector, it can potentially lead to crashes if a developer makes a mistake. While this mistake is likely to be noticed during development, there is a possibility of a typo causing side-effects that should not happen.

The grammar has been made more robust, as to not error out on statements containing unsafe divisions.
