--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I didn't have access to the preprocessed source and was lazy to prepare it myself, so I just copied the corresponding structure definition without C++ ctors/dtors, figured out what I thought would be a bitset_t, and tried if I can reproduce it with that. As I could, I have cleaned that up and replaced the fields so that they are named in a way to make it more readable what is going on. Now that I think about it, I think I could fix this differently by adding a flag to the store structures that it has been merged already, but I'll postpone that to next week, need to work on stage1 stuff this week.
