In debugging some experimental code in the kernel, I started seeing the following message, followed a little while later by a panic. Data modified on freelist: word 2 of object 0xc059e260 size 20 previous type devbuf (0x80 != 0xdeadc0de) My guess is that one of two things is happening. Either I'm writing to memory after I've free'd it, or I'm freeing something twice. Is it possible to tell from this message which one I'm doing? Or am I all wet and it really means something else?
