in reply to Duplicate "addresses" in hashrefs when printing

My first thought is what almut wrote already. Probably what happened is that you dumped HTTP::Connection=HASH(0xbef7360), it was then destroyed, and the memory was reused to make HTTP::OtherClass=HASH(0xbef7360) (so it has the same address).

It's also possible to bless an existing object into some other class. In that case, rather than HTTP::Connection=HASH(0xbef7360) being destroyed, it just got reblessed into HTTP::OtherClass somewhere.

Either way, you wouldn't see HTTP::Connection=HASH(0xbef7360) and HTTP::OtherClass=HASH(0xbef7360) at the same time, only in two separate dumps.

[davido]: I am not finding closing STDIN to be an adequate means of making getlogin return undef.
[Corion]: Maybe doing a double-fork (daemonizing) can make go that information away, but maybe not
[Corion]: But I think my knowledge of unix/Linux datastructures is several decades out of date, so I don't really know what information it keeps on processes
[oiskuu]: The useful bits that relate to your process can be found under /proc/self. What information are you thinking of? Tty name?
[tye]: I just daemonized and getlogin() still knew who I had been.
[tye]: perhaps loginuid ? Not that I concede that something not being in /proc means it is not useful.
