C++ Access violation reading location 0xFFFFFFFFFFFFFFFF when using __func__ identifier

Question

I am using Visual Studio 2017 and I set the project to use ISO C++14 Standard under C/C++->Languages

The debugger cannot recognize __func__ predefined identifier and it crashes if I try to use it as a string with error:

: Access violation reading location 0xFFFFFFFFFFFFFFFF

What am I missing to be able to use this identifier?

Code sample if needed

printf("%S\n", __func__);

Thanks

Answer 1

static const char __func__[];

printf() with a capital S as a conversion specifier is an extension that requires a wchar_t*.

Solution, use a lowercase s:

printf("%s\n", __func__);

or

std::cout << __func__ << '\n';
