Hello, I have been advised to send this report to this list, so here it is. My apologies if the report is not appropriate to the list (which I'm not subscribed to). Context : 486-DX2/66 w/ 16Mb RAM, 430Mo IDE (:-( ) HD, NE2000 network card. FreeBSD 2.2.7-RELEASE scratch install (Express mode, no additional software, no kernel recompilation...nothing...). This machine was supposed to be my very first FreeBSD machine (I'm afraid I'm quite penguinized....). After an installation w/o any problem, I just wanted to have the machine do something. Then I grabbed the latest rc5des binary distribution from http://www.distributed.net, installed it in /usr/local/lib/rc5des (owned by root). After configuration, root tried to launch rc5des (I know...that's a Very Bad Thing To Do) : maroussia# ./rc5des rc5des in free(): warning: junk pointer, too high to make sense. Segmentation fault (core dumped) OK....Let's ktrace all this : The last lines of 'kdump' are then : .../... (lot of stuff deleted) 200 rc5des RET read 1006/0x3ee 200 rc5des CALL read(0x4,0x98000,0x2000) 200 rc5des GIO fd 4 read 0 bytes "" 200 rc5des RET read 0 200 rc5des CALL close(0x4) 200 rc5des RET close 0 200 rc5des CALL connect(0x3,0xefbfd9e4,0x10) 200 rc5des RET connect 0 200 rc5des CALL fcntl(0x3,0x4,0x4) 200 rc5des RET fcntl 0 200 rc5des CALL write(0x2,0xefbfddc2,0x6) 200 rc5des GIO fd 2 wrote 6 bytes "rc5des" 200 rc5des RET write 6 200 rc5des CALL write(0x2,0x58007,0xb) 200 rc5des GIO fd 2 wrote 11 bytes " in free():" 200 rc5des RET write 11/0xb 200 rc5des CALL write(0x2,0x56b05,0xa) 200 rc5des GIO fd 2 wrote 10 bytes " warning: " 200 rc5des RET write 10/0xa 200 rc5des CALL write(0x2,0x576c3,0x26) 200 rc5des GIO fd 2 wrote 38 bytes "junk pointer, too high to make sense.

I hope that's true. If some futher investigation is required (strange commands, magic incantations, throwing Jack Daniels all around the PC...), feel free to ask... -- Christian Perrier To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
