Bruce,

Thanks for the reference.
I am indeed seeing that bug.

What I did was the solution of Darren that was listed in comment5, but
that did not work for me.
I was unaware of the cleansstate task.

Actually thinking of it, if in the flow:
$ bitbake virtual/kernel -c cleansstate
$ bitbake virtual/kernel -c menuconfig
$ bitbake virtual/kernel -c compile -f; bitbake virtual/kernel
the first two steps can be exchanged (so first menuconfig then
cleansstate, then menuconfig could force the cleansstate to run

(or menuconfig could run cleanstate befure doing the actual menuconfig work)

Best regards, Frans
