Subject: CRC Error on Second Extraction of File

First download this zip file: http://api.pgxn.org/dist/sha/1.1.0/sha-1.1.0.zip Then Run this command: perl -MArchive::Zip -E 'my $z = Archive::Zip->new; $z->read(shift); $z->extractTree; say +($z->membersMatching(qr{sha-1.1.0/README}))[0]->contents' sha-1.1.0.zip The output should be something like:

> format error: CRC or size mismatch while skipping data descriptor > at /var/virtuals/pgxn/perlbrew/perls/perl-5.14.2/lib/site_perl/5.14.2/Archive/Zip/ZipFileMember.pm line 189 > Archive::Zip::ZipFileMember::_skipLocalFileHeader('Archive::Zip::ZipFileMember=HASH(0x1f16cc8)') called at /var/virtuals/pgxn/perlbrew/perls/perl-5.14.2/lib/site_perl/5.14.2/Archive/Zip/ZipFileMember.pm line 395 > Archive::Zip::ZipFileMember::rewindData('Archive::Zip::ZipFileMember=HASH(0x1f16cc8)') called at /var/virtuals/pgxn/perlbrew/perls/perl-5.14.2/lib/site_perl/5.14.2/Archive/Zip/Member.pm line 960 > Archive::Zip::Member::contents('Archive::Zip::ZipFileMember=HASH(0x1f16cc8)') called at -e line 1 > 3
Then try the same command, but remove the `extractTree` call: perl -MArchive::Zip -E 'my $z = Archive::Zip->new; $z->read(shift); say +($z->membersMatching(qr{sha-1.1.0/README}))[0]->contents' sha-1.1.0.zip The README file contents will be output with no errors. I realize that there may be something wonky with this zip file, but I don’t understand why the README’s contents can be extracted once without error, but not a second time. Thoughts? Thanks, David

BTW, this is Archive::Zip 1.30 on Debian Linux (I think) and a perlbrew-built Perl 5.14.2.

Also occurs with Archive::Zip 1.31_04.
