Re^2: upgrade to 5.8.4 breaks code -- how to fix?

Does this bug hold with a perl 5.8.4 that is not compiled for threads (or multiplicity)? I'm just curious.

Does this bug hold with a perl 5.8.4 that is not compiled for threads It's in all versions of 5.8.4. It occurs whenever `my %h=()` or `my @a=()` is used in a place that's expected to to return a list, such as the last statement in a function called in list contect, or more unlikely, `@a=(my @b=())`. The optimisation to get rid of the `=()` accidently makes the expression return the array or hash itself rather than a list of it's contents. Thus leading to the 'bizarre copy of hash' error. Dave.

my %h=()

my @a=()
