Hmmm that should have the fix to net/rtsock.c then

If the free list is detected as being corrupted then the malloc log is
printed out, if memory is getting corrupted then the thing being
stomped will change but the "neighbour" - the bit of memory in use
just before the stomped memory may be the same which may offer some
clues - there is a variable malloclog_fuzz in kern/kern_malloc.c that
can be tweaked to widen/narrow the neighbour matching.
By the way you need DIAGNOSTIC defined as well to enable the checks.
