It's because e.g. an 8-byte unit (such as a long or - more often - a pointer) is being accessed at a non-8-byte aligned address (e.g. 0x12345 instead of 0x12340 or 0x12348). Usually because of bad programming, where a struct is copied into a block of memory as a series of bytes, and then the "struct" in that block is being used directly without first copying it into a properly aligned "real" struct. I'll see if I can have a look at snort for this; I prefer Chris concentrate on gcc, binutils, libc6-1 (which needs to be rebuilt with the latest kernel-headers, see bug #84238 :-) Paul Slootman -- home: [EMAIL PROTECTED] http://www.wurtel.demon.nl/ work: [EMAIL PROTECTED] http://www.murphy.nl/ debian: [EMAIL PROTECTED] http://www.debian.org/ isdn4linux: [EMAIL PROTECTED] http://www.isdn4linux.org/
