This is a cryptographically signed message in MIME format. --------------ms020506060709030904080705 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Hi all, I'm wondering if FreeBSD allows direct access to memory. What I'd like to do is try to force a Perl application to leak memory by simulating a dangling pointer that it's garbage collection system can't clean up. I'd then like to look at the raw memory address to find out if the data is in a state where it could later be retrieved. Is accessing memory like this permitted within the OS? If so, what type of editor would be used to do such a thing? Perhaps a snip of C code that one could pass in the address as a parameter?
