Something is wrong with bigger archives

[amacal]

I try to decompress just few bytes of two different files, one file works, the other one not. Both files work correctly with 7zip.

enwiki-20230501-pages-meta-history23.xml-p50555787p50564553.7z - works enwiki-20230501-pages-meta-history5.xml-p956483p958045.7z - doesn't work

I used the following code to test it:

#[tokio::main]
async fn main() -> Result<(), Box<dyn Error>> {
    let filename = "/wikipedia/enwiki-20230501-pages-meta-history5.xml-p956483p958045.7z";
    let mut stream = SevenZReader::open(filename, Password::empty()).unwrap();

    stream.for_each_entries(|entry, mut reader| {
        let mut buffer = [0; 16];
        println!("Reading entry: {:?}", entry);
        println!("{:?}", reader.read(&mut buffer[..]));
        println!("{:?}", std::str::from_utf8(&buffer));
        Ok(true)
    })?;

    Ok(())
}

output for enwiki-20230501-pages-meta-history5.xml-p956483p958045.7z:

@amacal Thank you for your report. There was a numerical overflow issue while decoding a large file. I will fix it and release a new version as soon as possible.

@amacal Version 0.2.11 has fixed this issue. You can update and try it out.

Cool! It works even for the biggest file in the dataset: enwiki-20230501-pages-meta-history10.xml-p5096070p5137514.7z
