Hi,

I tried again under the same conditions (just to make sure it wasn't
transient) and could reproduce the failure.

I also tried after disabling SMT (so the machine has only 20 visible
CPUs) and it succeeded.

Still with SMT disabled, I tried with forcing
DEB_BUILD_OPTIONS=parallel=200, and it failed. Can you reproduce it like
that?
