i played around with ActiveState's ActivePerl for Win32, and crashed Perl.exe with the following command: perl -e "$a="A" x 256; system($a)" I wonder if this bug isnt known?!? Because system() is a very common command.... Can anybody reproduce this?
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.
