Unitialized variable /usr/lib/llvm-19/lib/clang/19/include/cetintrin.h, skipfiles being ignored

Describe the bug
I'm getting an uninitialised variable warning for the clang cetintrin.h header, even though that file is in my skipfile:

-/usr/lib/llvm-19/lib/clang/19/include/*
-/usr/lib/llvm-19/lib/clang/19/include/cetintrin.h
-/usr/include/*

It's being detected due to getting (indirectly) included from other files

CodeChecker version
6.26.2

Expected behaviour
I expect skipfile provided via --skip to be honoured.

Hi @gizahNL,

The skipfile has two meanings: 1. it prevents the analysis of those .c/.cpp (i.e. not header) files, 2. it suppresses the reports even if they're coming from a header file.
By default case 1 happens, which means that the given source files are not analyzed, but reports may arrive from headers that are transitively included from the remaining, analyzed files. This happens in your case. Case 2 can be enabled by --drop-reports-from-skipped-files flag. Could you try if this fixes the issue?

Thank you!

I close this ticket, because I think the previous comment answers this question. Feel free to answer if there are still issues with skip functionality. Thank you!
