OK. I solved almost every problem except that `checkDeadSymbols()` removes the iterator position keyed by the temporary region representing the argument from the map before it is needed. Either I must somehow recognize that although the region is not "live" but the call whose argument it stores is not postchecked yet. I have no idea how to do this. Or, which I would prefer is to modify `SymbolReaper` so that `isLive()` returns true for temporary regions storing arguments of calls not postchecked yet. I have no idea either how to do this. Maybe should we take the `Expr` of `CXXTempObjectRegion`, use `ParentMap` to recognize whether it is a parameter for a `FunctionDecl`, but how to check whether the call for the function of the `FunctionDecl` is not postchecked yet? @NoQ, could you please, help me in this? Thx!
