I don't see the error HP C V7.3-018, so probably an unhelpful diagnostic sneaked in V7.3-020. It is true though that, given a sufficiently large object, you might lose data. Until the compiler gets a major overhaul, which may not be even on the roadmap for IA64, it's probably a case of verifying the restriction won't bite you, then disabling it in your build.
