Hi,
below some crash info. However, since kib@ made some fixes that seem to relate
to this, I shall rebuild my kernel with new sources.
At the time I was building various ports in a jail and asleep, so no other
contributing factors.
panic: free: address 0xc62e0e00(0xc62e0000) has not been allocated.

rollback sources to r196875 for proper source refs, in case r197041 does not
address this crash.
