SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***

STEPS TO REPRODUCE
1.  Run clazy-standalone on mainwnd.cpp from attached project, e.g.:
/usr/bin/clazy-standalone  mainwnd.cpp --  -x c++ -std=gnu++17 -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -I/usr/include/qt -I/usr/include/qt/QtWidgets -I/usr/include/qt/QtGui -I/usr/include/qt/QtCore -I./tmp

OBSERVED RESULT
clazy-standalone: /usr/include/llvm/Support/Casting.h:104: static bool llvm::isa_impl_cl<To, const From*>::doit(const From*) [with To = clang::CXXThisExpr; From = clang::Stmt]: Assertion `Val && "isa<> used on a null pointer"' failed.
Aborted (core dumped)
