Cppcheck syntax error code smell by C++/CLI

Question

New version of cppcheck found two major code smells named "syntax error" in following old lines of code:

System::Reflection::Assembly^ Foo(Object^ /* obj */, System::ResolveEventArgs^ args)
        {...}

and

catch (System::Exception^ /*e*/)

Errortext:

Cppcheck cannot tokenize the code correctly.

Any idea how to fix them? Is something wrong with the C++/CLI syntax?

It looks like a false positive for me, as the code compiles and works for a long time.

The C++/CLI Type^ syntax does not exist in C++, so this is certainly what CppCheck is confused with. — Quentin

When asking questions about errors, please always include the actual errors you get, copy-pasted as text in full and complete. — Some programmer dude

@ViktorBe No, the code shown isn't C++ code. That is also what cppcheck is telling you actually. — juanchopanza

As others have already pointed out, Cppcheck doesn't support C++/CLI. Try to use other analyzers. For example, PVS-Studio supports the analysis of C++/CLI and C++/CX (WinRT). — AndreyKarpov

Any idea how to fix them?

There is nothing you can do. C++/CLI is a dialect of C++, it is not standard C++. cppcheck works only with standard C or C++, so it will fail to understand C++/CLI code and thus give you the diagnostic you see. You'll need to exclude the source files that use C++/CLI code from your cppcheck check to avoid these errors.
