Hopefully this will save somebody else some time. ._.
We've been having a memory leak in libzip 0.9.3 and I wasted the last two days hunting it down. At first we didn't know what caused the memory leak obviously, but after a day and a half I finally tracked it down to libzip. I upgraded it to 0.11.2, but the leak was still there. There was even a bug report from about 2 weeks ago at their site about memory leaks. So we decided to say fuck it altogether and just switched ti miniz/minizip. It works as smooth as a seal's ass now. So if anybody here ever needs a library that can read ZIP files, don't use libzip.
