gzipDecode error: Uncaught RangeError: offset is out of bounds

[mbykovskyy]

I'm not sure if the issue is with this library or the Deno internals. I decode thousands of gzip encoded blobs in a loop, by calling gzipDecode.

for await (const serp of readCSVObjects(f)) {
    const res = await fetch(url)
    const body = new Uint8Array(await res.arrayBuffer())
    const html = gzipDecode(body)
    await Deno.writeFile(dest, html)
}

Over time gzipDecode fails with the following error.

error: Uncaught RangeError: offset is out of bounds
  getUint8Memory0().set(arg, ptr / 1);
                    ^
    at Uint8Array.set (<anonymous>)

    at gzipDecode (mod.ts:7:10)

I checked the gz blob and it was valid. I.e. I was able to decode it successfully with other tools.

Can you provide the smallest sample code that failed? So that I can locate the problem
