<iomanip>: put_time crashes, allocating a huge memory block

[ilya314]

Environment:
Microsoft Visual Studio Community 2019
Version 16.6.2
Open x64 Native command prompt for VS 2019.
Microsoft (R) C/C++ Optimizing Compiler Version 19.26.28806 for x64

Problem:
std::put_time crashed if all "tm" structure fields are equal -1.
If calling localtime_s with time_t > _MAX__TIME64_T then all "tm" fields filled by -1.
In real application put_time allocate tons of memory and application hang for some time.

#include <iomanip>
#include <sstream>
#include <iostream>
int main(int, char**)
{
    std::time_t t = 335303598060; // t > _MAX__TIME64_T
    tm t_tm;
    auto err = localtime_s(&t_tm, &t); // error, all fileds in t_tm = -1
    std::cout << "errno = " << err << "\n"; // errno = 22
    std::stringstream ss;
    ss << std::put_time(&t_tm, "%Y-%m-%d %H:%M:%S"); // crash, allocate tons on memory
    std::cout << ss.str() << "\n";
    return 0;
}

errno = 22
crash

Expected behavior:
put_time not crashed.

GCC/Clang (checked in Wandbox):
replace

    auto err = localtime_s(&t_tm, &t); // error, all fields in t_tm = -1
    std::cout << "errno = " << err << "\n"; // errno = 22

by

    localtime_r(&t, &t_tm);
    std::cout << "errno = " << errno << "\n";

Result:

errno = 0
12595-05-08 01:21:00

Why MS localtime_s has limitations for time_t maximum value?
As result we have an unsafe code, it is enough to pass a date >3000 year and the application crashes.

It seems the crash results from something like strftime. The following code will also cause the program to crash, either in debug or release mode.

#include <iostream>
int main() {
	tm t_tm{ -1, 0 };

	char buffer[100];
	strftime(buffer, 100, "%Y-%m-%d %H:%M:%S", &t_tm);
	//wcsftime has the same issue.
	return 0;
}

In debug mode:

In release mode:

Unhandled exception at 0x00007FF80ACA1208 (ucrtbase.dll) in test.exe:
