exceptions on windows not catched

[AdrianV]

This is a reopen of haxe issue HaxeFoundation/haxe#9780
Now I guess the problem is windows specific.

In the following code I tried to follow the problem. DateTools.format() calls the library function date_format which calls strftime. strftime should return 0 for an invalid format and date_format should then return a neko_error(). On linux this strftime ignores the wrong format so the code does not fail, but on windows this silently dies. I don't know whether strftime is the problem here or if all library code which returns neko_error() fails.

Same behaviour when I compile with Haxe 3.4 or 4.2beta. So it is not a regression.

class Main {
	static function main() {
		var date_format = neko.Lib.load("std", "date_format", 2);
		try untyped {
			var string = date_format(Date.now().__t, "%d.%m.%y %Q".__s); // This line should return neko_error()
			trace("here");  // this line is never reached on windows
			trace(__dollar__typeof(string));
			trace("here");
			if (__dollar__typeof(string) != __dollar__tstring)
				string = __dollar__string(string);
			trace(string);
			trace("here");
			trace(__dollar__ssize(string));
		} catch (e: Dynamic) {
			trace(e); // not catched
		}
		trace('Hello World'); // no output on windows
	}
}
