Behavior difference between `static` and not

[wcampbell0x2a]

I'm currently using this library for my squashfs library and i'm trying to let the user build this library statically: https://github.com/wcampbell0x2a/backhand/compare/master...add-xz-gzip-features

This library works great when building without the static features. However, when using this features the library gives different results breaking my tests and library when decompressing.

The first is an example of the beginning of the buffers being sent into the library:

I remind you, both examples are extracting the same file. All I see is that the following byte is different:

                                                                                           \/

Any help would be appreciated.
