My kernel (from sources of 13th) paniced with the following during "make
world".
May 15 18:25:00 caerdonn savecore: reboot after panic: ffs_blkfree: freeing free block
May 15 18:25:00 caerdonn savecore: writing core to /var/crash/vmcore.8
May 15 18:25:25 caerdonn savecore: writing kernel to /var/crash/kernel.8
I've a dump but gdb seems to have difficulties reading it so I can't "up"
and print structures.

"make world" itself got problems in the perl subdirectories during "make
depend" because it is calling perl which is not yet build.
