Apparently XZ embedded has a bug :( Not only our in-tree one, but the latest git of it is buggy too: $ git clone http://git.tukaani.org/xz-embedded.git $ cd xz-embedded/userspace $ make $ ./xzminidec </tmp/linux-3.8.tar.xz | wc -c ./xzminidec: Unsupported check; not verifying file integrity <......working for some time.......> 201330688 (xzminidec doesn't crash: exit code is zero). The peculiar thing is that 201330688 is exactly 0x0c001000. -- vda _______________________________________________ busybox mailing list [email protected] http://lists.busybox.net/mailman/listinfo/busybox
