FP: internalAstError

[Muhammad Javed]

I have the following scenario:

// test.cpp
#include <array>

template<typename T>
inline constexpr std::array<T, 1> cArray = std::array<T, 1>({T()});

template<typename T>
void foo(const T& aValue)
{
    if (cArray<T>[0] <= aValue)
    {
        return;
    }
}

In this scenario I have a templated constant that evaluates to an std::array. Performing a comparison against the contents of the std::array results in an internalAstError. Here are the cppcheck results:

Checking test.cpp ...
test.cpp:15:8: error: Syntax Error: AST broken, 'if' doesn't have two operands. [internalAstError]
    if (cArray<T>[0] <= aValue)

Storing the comparison in a bool results in this error:

Checking test.cpp ...
test.cpp:10:10: error: Uninitialized variable: comparison [legacyUninitvar]
    bool comparison = (cArray<T>[0] <= aValue);

It looks like cppcheck may be having trouble with a templated variable that evaluates to an std::array? I hope this information helps, thanks!

EDIT: Posted faulty code on accident, however it should be fixed now
