When I run tests for the stage #yx6 I get: ```bash [tester::#YX6] Running tests for Stage #YX6 (File Search - Recursive search) [tester::#YX6] [setup] echo "raspberry" > "dir/fruits-9393.txt" [tester::#YX6] [setup] echo "pear" >> "dir/fruits-9393.txt" [tester::#YX6] [setup] echo "carrot" > "dir/subdir/vegetables-8596.txt" [tester::#YX6] [setup] echo "celery" >> "dir/subdir/vegetables-8596.txt" [tester::#YX6] [setup] echo "cauliflower" >> "dir/subdir/vegetables-8596.txt" [tester::#YX6] [setup] echo "peas" > "dir/vegetables-6093.txt" [tester::#YX6] [setup] echo "carrot" >> "dir/vegetables-6093.txt" [tester::#YX6] [setup] echo "cucumber" >> "dir/vegetables-6093.txt" [tester::#YX6] $ ./your_program.sh -r -E .+er dir/ [your_program] thread 121 panic: reached unreachable code [your_program] /usr/local/zig/lib/std/posix.zig:5244:18: 0x10f5b72 in lseek_SET (main) [your_program] .BADF => unreachable, // always a race condition [your_program] ^ [your_program] /usr/local/zig/lib/std/fs/Dir.zig:361:40: 0x10f031b in nextLinux (main) [your_program] posix.lseek_SET(self.dir.fd, 0) catch unreachable; // EBADF here likely means that the Dir was not opened with iteration permissions [your_program] ^ [your_program] /usr/local/zig/lib/std/fs/Dir.zig:345:34: 0x10e6847 in next (main) [your_program] return self.nextLinux() catch |err| switch (err) { [your_program] ^ [your_program] /usr/local/zig/lib/std/fs/Dir.zig:680:30: 0x10e5d20 in next (main) [your_program] if (top.iter.next() catch |err| { [your_program] ^ [your_program] /app/src/main.zig:48:27: 0x10eaf1c in recursiveSearch (main) [your_program] while (try walker.next()) |entry| { [your_program] ^ [your_program] /app/src/main.zig:25:42: 0x10ec954 in main (main) [your_program] matched = try recursiveSearch(args[4], pattern, allocator); [your_program] ^ [your_program] /usr/local/zig/lib/std/start.zig:656:37: 0x10e4afa in posixCallMainAndExit (main) [your_program] const result = root.main() catch |err| { [your_program] ^ [your_program] /usr/local/zig/lib/std/start.zig:271:5: 0x10e46ad in _start (main) [your_program] asm volatile (switch (native_arch) { [your_program] ^ [your_program] ???:?:?: 0x0 in ???

Hey @danilovict2, setting `.iterate = true` should resolve the issue. ![image](https://canada1.discourse-cdn.com/flex003/uploads/codecrafters/original/3X/a/4/a41d6e9fc01fe0530d782cce4616d455dddb2f7a.png) > ---
