SUMMARY
clang-tidy will seg fault when running the "clazy-compare-member-check" check
with ClazyClangTidy.so plugin loaded (introduced in 1.17).
STEPS TO REPRODUCE
1. main.cpp
#include <QApplication>
int main( int /*unused*/, char** const /*unused*/ )
{
}
2. CMakeLists.txt
cmake_minimum_required( VERSION 3.22 )
project( template-qt-project )
find_package( gentex-cmake 3.77 REQUIRED )
find_package(Qt6 REQUIRED COMPONENTS Core Widgets)
add_executable(template-qt-project main.cpp)
target_link_libraries(template-qt-project PRIVATE Qt6::Core Qt6::Widgets)
3. mkdir build && cd build
4. cmake -DCMAKE_EXPORT_COMPILE_COMMANDS=ON -G Ninja ..
5. cmake --build .
6. /usr/bin/clang-tidy -checks=clazy-compare-member-check -p=.
-load=ClazyClangTidy.so --warnings-as-errors=* /home/path/to/your/main.cpp
OBSERVED RESULT
Stack dump:
