There were memory leaks in v5.8.0 as I learnt from
this post; BTW this specific problem was solved in v5.8.6 (don't know which release solved it actually). They're probably unrelated memory leak problems, but I wouldn't bet on v5.8.0 not leaking.
Flavio (perl -e 'print(scalar(reverse("\nti.xittelop\@oivalf")))')
Don't fool yourself.
