What are you trying to do over here? The various variables being used over here are not even defined? Could please paste a complete code?

U say u have defined 3 arrays - a, b and probably c - never used???

By the way .. there is no need to check for NULL once u use new to allocate the memory. It throws an exception if its unable to serve its purpose.

Suggestion - Review ur query !

It doesn't seem to be that huge array: only 256Kb. Except for very dirty style, in principle this code seems OK. Try to create a small self-sufficient code snipped producing the error.
