My experience is that LLVM uses of iterator is very coherent with what to expect from C++, and I never had any issue on this aspect. Iterator invalidation is pervasive in the STL containers, and as a C++ programmer you are supposed to know what type of container you're iterating on (in LLVM iterating over a basic block is a linked-list, iterator are not invalidated for instance).
