in reply to Re^3: random behaviour of perl hashes
in thread random behaviour of perl hashes

According to "perlrun":

The default behaviour is to randomise unless the PERL_HASH_SEED is set. If Perl has been compiled with "-DUSE_HASH_SEED_EXPLICIT", the default behaviour is not to randomise unless the PERL_HASH_SEED is set.

perhaps ActiveState Perl is compiled with -DUSE_HASH_SEED_EXPLICIT ?

perl -V
[download]

might tell you whether that is the case.

perl -v returns (among many other data):

-GF -W3 -MD -Zi

-DNDEBUG -O1 -DWIN32 -D_CONSOLE -DNO_STRICT -DHAVE_DES_FCRYPT -DNO_HASH_SEED -DUSE_SITECUSTOMIZE -DPERL_IMPLICIT_CONTEXT -DPERL_IMPLICIT_SYS -DUSE_PERLIO -DPERL_MSVCRT_READFIX

It would seem not, unless -DNO_HASH_SEED has a similar effect.
