Hi Julian,
The handful of times I=E2=80=99ve seen this occur in the past =
with other compiler versions, it=E2=80=99s been caused by an incomplete =
buildworld and/or tainted .OBJDIR. It might be a good idea to wipe out =
${OBJROOT} and start buildworld from scratch, to see if the issue =
persists.
Best of luck,
-Enji
