Package: advancecomp
Version: 1.20-1
Severity: normal

Dear Maintainer,

advzip sometimes fails with this error message:

   Failed read end of central directory on 00-archive/20170303.zip

the zip file itself can be handled fine by other utilities.

After experimenting with a number of zip files, it seems this error occurs
for zip files larger than 4GB, probably caused by a 64 bit uncleanlyness
in the code.

This is corrobated by strace'ing it - for example, when running "advzip -2
-z" on a zip file with size 0x1e289f20a, it does a lot of llseeks around
0x0e2896000 before bailing out, which is suspiciously near the lower 3
2bits of the filesize.
