Hi folks
I'm trying to use netbsd 4-99-19 under the parallels desktop but I
have this some problems with this. When I try to make pkgsrc/devel/
gmake I got panic with non diagnostic kernel or this error message
with DIAGNOSTIC kernel:
Data modified on freelist: word 0 of object 0xc0faa8b0 size 8
previous type bar (0x61732e74 != 0xdeadbeef)
Data modified on freelist: word 0 of object 0xc0faa730 size 8
previous type bar (0x61732e74 != 0xdeadbeef)

these lines are printed from kern/kern_malloc.c

478 printf("Data modified on freelist: "
479 "word %ld of object %p size %ld previous type %s "
480 "(0x%x != 0x%x)\n",

482 "bar", *lp, WEIRD_ADDR);
