hi folks,

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

It's hard to tell, could be either a CRT or a perl (build) error as noted in the thread.
