broken jpg file causes assertion failure

[rtmrtmrtmrtm]

When I run this program:

use zune_jpeg::zune_core; use std::fs::read; fn main() { let data = read("ass4a.jpg").unwrap(); let options = zune_core::options::DecoderOptions::default() .set_strict_mode(false) .set_max_width(usize::MAX) .set_max_height(usize::MAX); let mut decoder = zune_jpeg::JpegDecoder::new_with_options(&data, options); decoder.decode_headers().unwrap(); let mut out = vec![0;decoder.output_buffer_size().unwrap()]; decoder.decode_into(&mut out).unwrap(); }

on the attached JPEG file ass4a.jpg, with zune-jpeg 0.4.11, I get this assertion failure:
