Presubmit patch for this PR

I have realised that marking the symbol with the location that it was allocated
at is somewhat over ambitious and that a bit field would be sufficient.

I don't have time today to recompile from scratch but will return to this PR in
the coming day or two.

It regtests without errors.

Cheers

Paul
