In order for checker and similar products (purify, Electric Fence) to
prevent the propagation of undefined values, dataflow analysis at
compile-time is required. The unused value from memory is read into a
register and then is sometimes not used. Because checker is doing its
thing at run-time, it is too late for the dataflow analysis.
Well, just as it can trace pointers, it could trace values coming from
unitialized memory.
