false positive - syntaxError brace initialization with explicit operator call

[Joel Shuman]

Hello,
I just wanted to report a false positive syntaxError. My team uses brace init everywhere we can and we have some templates that make calls using explicit operator calls to get a value. Here is a simple example without a template.

#include <iostream>
#include <cstdint>

struct callable
{
    int operator()() { return 42; }
};

int main()
{
    callable c;
    std::int32_t const myint = c.operator()(); // <-- No syntaxError from cppcheck
    std::cout << myint << '\n';

    std::int32_t const anotherint{ c.operator()() }; // <-- This produces a syntaxError from cppcheck
    std::cout << anotherint << '\n';
}

This does not seem specific to the call operator. I have also seen this false positive with auto const data{ operator->() };

I can work-around this easily enough, but I wanted to report the false positive.

I tested this using cppcheck 2.18.3.

Thank you!
Joel

Thanks for reporting. I filed https://trac.cppcheck.net/ticket/14151 about it.
