Dino Distefano 7002d0d24c Adding a test in symbolic execution when a dangling uninitialized pointer is dereferenced Summary: The symbolic execution was not stopping in case an unitialized dangling pointer was passed to a function and then dereferenced inside the callee. What would happen is that a wrong footprint would be added to the unititialized pointer at the end of the function call in the caller proposition. This checks that if we do: frame * new_footprint checks that we do not add heap predicates to the frame into uninitialized local variables. If we can identify the variable then we raise a danglind pointer dereference. If instead we cannot give a good explanation we give an internal error. The latter case should be temporary. We should find a general way to raise dangling pointer deref instead of the internal error. I also fixed the model of getc that was the way I found the problem.		9 years ago
