Basic problem

here is the faulting code

std::cout << "tokenType 0" << std::endl;
noSuchType::error.push([](noSuchType e) -> int {return 0;});
std::cout << "tokenType 1" << std::endl;

and here is the output it produces

tokenType 0

but if i put in return 1 instead of return 0 like this:

std::cout << "tokenType 0" << std::endl;
noSuchType::error.push([](noSuchType e) -> int {return 1;});
std::cout << "tokenType 1" << std::endl;

i get the expected output:

tokenType 0
tokenType 1

more relevant code for context.

code that may call the functions inside noSuchType::error

    template<typename issueType>
    void invoke(issueType e)
    {
        std::cout << "invoke<" << typeid(issueType).name() <<">"<< std::endl;
        switch(e.Action)
        {
            case(action::error):
            {
                //std::cout << "invoking: " << issueType::error.top() << std::endl;
                if(issueType::error.top()(e) == 1)
                    throw e;
                break;
            }
            case(action::warning):
            {
                //std::cout << "invoking: " << issueType::warn.top() << std::endl;
                issueType::warn.top()(e);
                break;
            }
            case(action::info):
            {
                std::cout << "invoking: " << issueType::info.top() << std::endl;
                issueType::info.top()(e);
                break;
            }
        }
    }

    class fatal : public issue {
    public:
        const static action Action = action::error;
    };
    class noSuchType : public fatal {

Debugging

• I have checked if this is actually an issue inside issues::invoke and the stack trace is just messed up, but that does not appear to be the case.

• The output that results from return 0 also occurs for return 2

• return 0,return 1 and return 2 all compile without any warnings related to the code in question

I can obviously provide more context if necessary but i feel like this should suffice.
I Apologize for any spelling mistakes or grammatical errors, English is not my first language.
Thanks for you help in advance.
