What steps will reproduce the bug?
This will crash the entire program not even recoverable with a try statement
import fs from "fs";
fs.stat("ᜄȺy𐞲:𞢢𘴇𐀀'¥3̞[<i$", function onstat (err, stat) {
console.log("unreachable");
});logs:
Assertion failed: w_target_len == 0, file c:\ws\deps\uv\src\idna.c, line 408
How often does it reproduce? Is there a required condition?
I think this might be windows only based on the libuv source
What is the expected behavior? Why is that the expected behavior?
Throw an error/call the actual callback with the error.
What do you see instead?
The entire program crashes
Additional information
I discovered this by performing a fuzz test on my remix.js site which uses express.js which uses fs.stat.
This can take down a production server no matter their routes with just a HTTP GET request as long as they have express.static or similar behaviour for static file serving.
