hi folks,

i played around with ActiveState's ActivePerl for Win32, and crashedPerl.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 commoncommand....

Can anybody reproduce this?

I put together a little advisory on my website, including versioninformation and a debugger output (Drwatson):

PS: Due to travel activity, i will not be able to respond to mailswithin the next 8 days!


Regards,

Oliver
