Bug in cloop_utils ? -> Can't create a compressed image of 4GB

[Epicuro]

Dear all Ubuntu developers,

I think there's something wrong with the ubuntu/debian cloop-utils package.

I have a 4294967296 bytes (4GB) file and I want to create a compressed fs.

When I issue the command create_compressed_fs extracted_fs 65536 it
produces the following error :

Opening input: File too large

I've looked into 2.01.5-2ubuntu2 sources and the README file says it has
64 bit pointers so it should be able of dealing with files larger than 4GB
...

I'm using Hoary RC with the default configuration/kernel/libc :
