With my perls, the original one-liner works as intended for 5.8.8 up to and including 5.18.0.
But with 5.20.0 I get the same as you.

The srand documentation contains this: 
However, there are a few situations where programs are likely to
want to call "srand". One is for generating predictable results,
generally for testing or debugging. There, you use
"srand($seed)", with the same $seed each time.

That suggests to me that srand(42) should produce identical results whenever it is called.
I can't find anything in the docs that indicate there have been changes to srand - grepping 5.20.0 perldelta for srand produced no hits.

However, there *is* mention (in perldelta) of changes to rand with 5.20, and I guess that if the rand implementation has changed then the same seed will no longer yield same results.
I do think that the breakage of srand($seed) between 5.20 and earlier perls should have been spelled out in the srand documentation ... probably worth a bug report from someone who cares.

Cheers,
Rob
