zlib unpacking yields in assertion error

[andris9]

Node.js: v0.5.9, v0.5.8
Systems: OSX, Debian Lenny

When trying to unpack (gunzip or inflte) data with zlib, assertion error occurs.

Using he following script (slightly modified from the zlib section in node.js manual, createGzip changed to createGunzip) and the output length (unpacked.txt) should be 32kB or larger:

var zlib = require('zlib');
var gzip = zlib.createGunzip();
var fs = require('fs');
var inp = fs.createReadStream('packed.gz');
var out = fs.createWriteStream('unpacked.txt');

inp.pipe(gzip).pipe(out);

The following error occurs:

node: ../src/node_zlib.cc:104: static v8::Handle<v8::Value> 
    node::ZCtx<mode>::Write(const v8::Arguments&) [with 
    node::node_zlib_mode mode = INFLATERAW]: 
    Assertion `in_off + in_len <= Buffer::Length(in_buf)' failed.
Aborted

I can reproduce. Investigating.

wow, that was fast, thanks!

Failing assert + reproducible test = easy fix :)
