Crash in ipcdetail::get_bootstamp when multi thread racing and winapi::get_last_bootup_time failed on Windows

[lwttai]

Crash in bellow function where windows_intermodule_singleton<windows_bootstamp>::get() return null which cause invalid access.

// boost\interprocess\detail\shared_dir_helpers.hpp: 54 inline void get_bootstamp(std::string &s, bool add = false) { const windows_bootstamp &bootstamp = windows_intermodule_singleton<windows_bootstamp>::get(); if(add){ s += bootstamp.stamp; } else{ s = bootstamp.stamp; } }

Debug code example: ` std::atomic_bool g_start = false;

int main() {

auto thread_func = []() {
	while (true) {
		if (g_start) {
			boost::interprocess::named_mutex::remove("aaa");
		}
	}
};

std::thread t1(thread_func);
std::thread t2(thread_func);
std::this_thread::sleep_for(std::chrono::seconds(1));
g_start = true;
t1.join();

} When two thread enter intermodule_singleton_common::initialize_singleton_logic(boost\interprocess\detail\intermodule_singleton_common.hpp: 98)，one is waiting inif(previous_module_singleton_initialized == Initializing)while another is try to initialize the instance inif(previous_module_singleton_initialized == Uninitialized)`. If exception throw in the initialize function, the initial thread will set the initialized state to broken which cause the waiting thread stop waiting and return a nullptr without any initialized failed checking or throw any exception.

As the example, windows_bootstamp's construction will throw exception when winapi::get_last_bootup_time return false witch will happen when some user environment can't find System Event Log 6005(event log started) or any other errors.
