Hello Kris,

So it's harmless?

As for debugging, I compiled kernel with:
makeoptions     DEBUG=-g
options         KDB
options         KDB_TRACE
options         DDB

To have coredump, if system crashes (I didn't oticed any slowdown, so
I guess it doesn't hurt)

Are those last three options necessary to get core? Or is only
DEBUG=-g needed?

Trying to outsmart a compiler defeats much of the purpose of using one.
