Hi!

I created 2 zip-files by OS X (via context menu -> Compress Files)

One is 6.25 GB and second is 3.78 GB.

Results:

• Unzipping 6.25 GB zip-file using OSX
• [!] Unzipping 6.25 GB zip-file using Minizip == ERROR
• [!] Unzipping 6.25 GB zip-file using standard Windows unzipper == ERROR
• [!] Unzipping 6.25 GB zip-file using 7-zip (Windows version) == SOME ERRORS. While unzipping, 7-zip says that some files have unsupported compression method.
• Unzipping 3.78 GB zip-file using OSX
• Unzipping 3.78 GB zip-file using Mizinip.
• Unzipping 3.78 GB zip-file using standard Windows unzipper
• Unzipping 3.78 GB zip-file using 7-zip (Windows version)

Error in unzip.c, started at #1060

if (unz64local_getLong(&s->z_filefunc, s->filestream, &uMagic) != UNZ_OK)
err = UNZ_ERRNO;
else if (uMagic!=LOCALHEADERMAGIC)
err = UNZ_BADZIPFILE;

Its got a wrong 'uMagic' in 'unz64local_getLong' that is not the same as 'LOCALHEADERMAGIC'.

So, looking that OSX is compressing zip-files (which are bigger than 4 GB) by own method that Windows and Minizip can't recognize?
