Description of problem:
SSIA

Version-Release number of selected component (if applicable):
zip-2.31-1.2.2

How reproducible:
Always, but only on i368 (and possibly other 32-bit arches). x86_64 gives this
output: zip error: Entry too big to split, read, or write (file exceeds Zip's
4GB uncompressed size limit)

Steps to Reproduce:
e.g.:
1. dd if=/dev/zero of=testfile bs=1M count=4097
2. zip testfile.zip testfile
  
Actual results:
Segmentation fault

Expected results:
Hmm, I don't know :) . Either the message it prints on x86_64, or just success.
The question is if zip is able to work with >4GB files or not. In either case,
it shouldn't crash.
