5.8.2 and later have hashes that are deterministic until the data is pathological. And the pathological checks kick in very late. Only 5.8.1 has true random hashes (not 5.8.0) and even without compile time changes (IIRC) you can always force deterministic hashes with environment variables. > 5. Localizing tied arrays and hashes is broken in 5.8. We tie and localize %ENV. I wasn't aware of this. Or at least, it doesn't ring a bell. Is perl5-porters aware of this? Is this a known change in behaviour? Not that this invalidates your reasons for needing to stick to 5.6.x Nicholas Clark
