I can confirm this for Perl v5.8.0 built for MSWin32-x86-multi-thread
(Binary build 805 provided by ActiveState Corp.) on W2K.
My first thought was that the nested double-quotes maybe the reason,
but even
perl -e "$a='A' x 256; system($a)"
crashes.
perl -e "system('A'x256)"
chrashes also btw.
Kind regards, Axel Beckert
