I got a warning like this: testing in free(): warning: modified (chunk-) pointer. testing is the name of the executable I am running. Could anyone tell me what this warning means? What may be the effect of this code when I shift it to kernel with due modifications? I have put this code in kernel and when this gets executed, I get a panic immediately or some time later. This happens even if I don't execute any command after this code. When the kernel reboots, it reports file system inconsistencies and goes into single user mode. When I do 'fsck' and reboot it, it gets rebooted to multi-user mode. I am totally lost. Any help in this regard will be appreciated. thanks and regards Madhavi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
