Using Zig 0.15.1 on MacOS. This could very well be user error, but I am not sure how. Maybe I am doing it wrong, or it might be a bug? I have just upgraded to 0.15.1, and the fromFilePath command panics when I do this:
const temp_filename = "/tmp/temp.out.png";
try zstbi.Image.writeToFile(img, temp_filename, format);
var temp_buffer: [4192]u8 = undefined;
debug("zigimg load file from {s}", .{temp_filename});
var image = try zigimg.Image.fromFilePath(allocator, temp_filename, &temp_buffer); // <-- panics
// var image = try zigimg.Image.fromFilePath(allocator, temp_filename, temp_buffer[0..]); // <-- panics
defer image.deinit(allocator);[default] (debug): zigimg load file from /tmp/temp.out.png
