<![CDATA[Crash bei member function: const std::string&amp; s = {}]]>Hi!

Kann mir jemand erklären, warum es zum Crash kommt?

void FuncX(const std::string& s = {})
{
	;
}

struct STest
{
	void Func(const std::string& s = {})
	{
		;
	}
};

int main()
{
	FuncX(); // OK: basic_string()

	STest t;

	t.Func(); // CRASH (invalid null pointer): basic_string(const _Elem *_Ptr)
}

Danke!

Edit: Sollte eigentlich der Initializer_list Konstruktor aufgerufen werden. Was hasten fürn Compiler?

Mh, wahrscheinlich mal wieder der MSVC 😞
