Re: bitbake is corrupting my files during unpacking

well apparently this is caused by the unzip binary that is compiled by 
the openembedded unzip recipe.
If I unzip the same zip file with the unzip binary that is shipped with 
my system(manjaro) then the files are not corrupted but when I use the 
unzip binary compiled by the openembedded recipe I get error and file 
corruptions.
These are some of the errors I get when unzipping with the openembedded 
unzip:

This error happens to multiple files where the file is symlinked to the 
content of the file and not to a path !
Where should I report this bug ? openembedded ? unzip upstream ?
