![]() More information about this specific check can be found at c33001 | Microsoft Docs. In summary, clearing a VARIANT object that was not properly initialized can result in many random problems, including crashes, memory errors, etc. Running code analysis on this code will give a few warnings. ![]() 1 #include ģ2 VariantClear(pv) // Warning C33001 here The following example is intentionally made convoluted enough to demonstrate the challenge of finding the root cause for warnings from a path-sensitive check. It can be best demonstrated with some example code with a known defect. Let’s review the usual challenges we have when a static code analysis check tells us there is a defect in our code. In this blog post, we would like to reintroduce an existing Visual Studio feature that has been there to help with this challenge, and to highlight the big improvements we have made to the feature which will make it easier and more compelling to use. How would you be able to quickly find the root cause and fix it? Imagine a warning where the effect of the bug is detected tens or hundreds of lines below the root cause of the bug, and the code against which the defect is reported looks completely legitimate. ![]() It is natural that developers find it harder to find the root causes for some of these more complex warnings. As such, they can find defects that are harder to find through syntactic checks alone or through data flow analysis. ![]() Some of the checks work harder than others, analyzing the code deeper by simulating runtime behavior. To make your C++ coding experience as safe as possible, the Microsoft C++ Code Analysis has added new checks and improved existing ones to help you prevent bugs before they find their way into your products. ![]()
