Then if the h == 0 check is true, we exit from the function’s body. During initialization impl->delayedHeight, the h variable has non-zero value. Thus, impl->delayedHeight is false.

Why you should check values of public methods’ parameters
▻https://hownot2code.com/2021/10/22/why-you-should-check-values-of-public-methods-parameters

This note will answer the question – why PVS-Studio considers parameters of public methods potential sources of tainted data. The analyzer can issue warnings if such parameters haven’t been checked before use. The point is that undue confidence in external data may lead to various vulnerabilities – SQLI, XSS, path traversal and others. Most obvious … Continue reading Why you should check values of public methods’ parameters
