           Product: clazy
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: REPORTED

SUMMARY
When testing clazy 1.8 on current Debian unstable using LLVM 9, the
qt6-deprecated-api-fixes & qt6-qlatin1stringchar-to-u tests fail when run on
Linux architectures (at least on x86_64 and i386).

STEPS TO REPRODUCE
1. build clazy on a Linux architecture using LLVM 9
2. run the test suite, either from the build directory, or after installation
