Ahh... my bad for misreading ;)
Rather than patching things this way, you could always use the array_source device defined in <boost/iostreams/device/array.hpp>. A very simple wrapper can also be written around a std::vector, or you can use the array_source directly on the internal data of the std::vector.
You then use a filtered_source, and push back the gzip_decompressor followed by the array_source, like the earlier example in this thread.
That is exactly what is not working. And the patch is to make it work. I actually found out that there is a ticket for this problem already.

Thank you eg, Chris,
But I have probably misled you a bit with my post. The gzipped data is actually in memory (inside the storage variable), and I wanted to have a gzip_decompressing stream fromT that.
for no I am using this patch
