Function invoked whenever a complete path is found.

virtual void Rose::BinaryAnalysis::FeasiblePath::PathProcessor::nullDeref ( IoMode  ioMode,
const InstructionSemantics2::BaseSemantics::SValuePtr addr,

Function invoked whenever a null pointer dereference is detected.

The ioMode indicates whether the null address was read or written, and the addr is the address that was accessed. The address might not be the constant zero depending on other settings (for example, it could be an unknown value represented as a variable if "may" analysis is used and the comparison is not limited to only constant expressions).

The instruction during which the null dereference occurred is also passed as an argument, but it may be a null pointer in some situations. For instance, the instruction will be null if the dereference occurs when popping the return address from the stack for a function that was called but whose implementation is not present (such as when the inter-procedural depth was too great, the function is a non-linked import, etc.)
