- How do I access reference counted pointers in GDB?
- Objects such as DynInsts are reference counted, making it slightly harder to obtain the data inside. In gdb you must access them through the pointer that is stored in the ref counted pointer, which is called data. Thus given a ref counted pointer ptr, in gdb you would say ptr->data to get the pointer to the actual object.
