Los Altos, California-based Pure Software Inc is promising to heighten the reliability of any C or C++ program with a home-grown technology that uses instruction-level checking. Unlike traditional source code debuggers, Purify uses a process – for which patents are pending – that performs instruction-level checking of the object code, combing it for illegal memory accesses and memory leaks. It then identifies their causes in the original source code, and checks all code including third-party libraries. The product supports code on Sparc boxes under SunOS 4.1.1 along with CC, cc and gnu 1.X compilers. List price is $2,750 for a single floating network licence. Availability is immediate.
