After many battle with `ocamlbuild`, `g++`, `SIGSEGV` (thanks Jeremy) and `LD_LIBRARY_PATH`, we have a inverted stub of decompress (and a plugin of `ocamlbuild` to build the shared library). And we have a benchmark to compare the decompress with zlib or another Lz77 compressor at this repository:

https://github.com/dinosaure/lzbench

You just put the `libdecompress.so` in `decompress` directory and `make && LD_LIBRARY_PATH=./decompress ./bench -edecompress,4/zlib,4 something` to see the very non-efficient implementation of zlib in OCaml! So if someone is interested by the optimization of decompress, we have a good way to improve this now.

Now, I can release the 0.4 version just after I fix a bug with a compression with level = 0. Thanks all for your attention on this project.

Cheers,

I'm curious about the minor bug with reverse stubs C code.  If it's a
problem in ctypes, could you please give some details in a GitHub
issue (https://github.com/ocamllabs/ocaml-ctypes/issues/)?
