hi there, i've installed emulators/linux_dist-gentoo-stage3 and grabbed a snapshot from the ltp git repository (http://ltp.sourceforge.net/). as expected some tests failed because i'm using compat.linux.osrelease: 2.6.16 which is still missing a few linux syscalls, ipcs and ioctls.
however i also noticed REDZONE reporting buffer overflows. i'm only a user and not a developer so i don't know if the ltp is to be blamed or if the problem lies within the linuxulator. i'm running 9.0-CURRENT (r196879). as i mentioned before i'm using 2.6 linux kernel emulation. here are the buffer overflow reports: Sep 9 14:12:42 otaku kernel: REDZONE: Buffer overflow detected. 9 bytes corrupted after 0xcc28c483 (3 bytes allocated).
