I think the real difficult thing in path sensitive program analysis (or
symbolic execution) is not the lack of decision procedures, but the
translation of arbitrary pointer operations and library function calls in
C/C++ program into the mathematics supported by the automated theorem
Almost every concept in the computer program except memory address has a
counterpart in mathematics. I have tried to simulate memory by arrays in
symbolic execution. But I found it is inadequate.
