Failed to compile valid code

[valeros]

Hello!

It looks like I've run into code that Cppcheck is not able to compile. The original code can be found here. I prepared a stripped code snippet:

#include <stdint.h>

extern "C++"
template <typename T, typename ...TConstructorArgs>
T* test (int n, TConstructorArgs... TconstructorArgs)
{
    /* Index out of bounds */
    int arr[10];
    for(int i=0; i < 11; i++) {
        arr[i] = 0;
    }

    return nullptr;
}

The latest Cppcheck reports the following error message:

Checking core_esp8266_features.h ...
Defines:
Undefines:
Includes:
Platform:win64
core_esp8266_features.h:4:1: error: syntax error [syntaxError]
template <typename T, typename ...TConstructorArgs>

Cppcheck command

cppcheck --debug-warnings --language=c++ -v --std=c++20 core_esp8266_features.h

Thanks in advance!
