It's compiler and OS specific, Visual studio sets different kinds of memory to different values so that in the debugger you can easily see if you have overun into into malloced memory, a fixed array or an uninitialised object.
Somebody will post the details while I am googling them...

When and why will an OS initialise memory to 0xCD, 0xDD, etc. on malloc/free/new/delete?

I have a list of email addresses from people that use my app. Is it possible to query for their facebook public data by email address?

Thanks Richard.
