Description Christian Franke 2010-10-20 15:54:48 UTC 
If there is -malign-double in CFLAGS, app-arch/unzip builds fine, however it fails to unpack any zip file. This is on x86.

The ebuild might filter -malign-double.

Reproducible: Always

Steps to Reproduce:
1. add -malign-double to CFLAGS
2. reemerge app-arch/unpack
3. try to unpack a zip file

Actual Results:  
sccd unzip60 # ./unzip testmake.zip
Archive:  testmake.zip
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
unzip:  cannot find zipfile directory in one of testmake.zip or
        testmake.zip.zip, and cannot find testmake.zip.ZIP, period.

You can resolve this by removing -malign-double from CFLAGS. Gentoo does not support it.
