even if it IS deterministic in --num-threads=1, and is Not deterministic in multi-thread case?

Might changing the ODR uniquing algorithm be a solution then? (That is what I described in some previous message - do not reuse existing type declarations, but generate an artificial compile unit containing the types)? Such artificial compile unit containing the types might be generated in the deterministic way.
