Purify is (commercial) software put out by Pure/Atria. It detects errors
during software execution by catching calls and inserting checks at
different places. It is primarily used to catch errors where memory is
allocated and not freed, as well as writes beyond allocated space
(although it also catches a number of other problems, such as
use of uninitialized memory, etc). It is NICE software, but it is also
fairly expensive.
It runs on Solaris, Irix, AIX (I believe), NT, and a few others. You can
check out Pure/Atria's web page at www.pureatria.com for more info...
