[cppia] Exception control flow breaks with local functions in jit mode

[tobil4sk]

function other() {
	throw new haxe.Exception("hi");
}

function main() {
	sys.thread.Thread.create(() -> {
		other();
		trace("Continued past exception!");
	});
	Sys.sleep(1);
}

When the exception occurs in a different function, the program just continues running past it...

src/CppiaTest.hx:8: Continued past exception!

If the exception is instead thrown in the thread function, then the execution stops as expected.

Turns out it's not specific to threads, it is reproducible with any local function, and was reported in the past in #876
