I think that it came in with 5.005_00. Certainly, it's in 5.005_03, which is the earliest version I can find precompiled: $ perl5.00503 -le '$a = qr/(.*)/; $] =~ $a; print $1' 5.00503 So whatever the actual cause of the bug leading to the report is, it wouldn't seem to be what the reporter thought it was.
