Which version of unzip do you have (unzip -v, look for ZIP64_SUPPORT)?
It seems that (some version of?) OS X ships with an older unzip which
can't handle big files:

Is the following check (zip archive with files bigger than 4GB) skipped,
e.g. because ZIPINFO is missing?  Otherwise I would expect it to fail as
well.
