Hi,
I add a prefetcher into zsim, using all g_vector/g_map, when running one program instance it will finish normally, but when running two same instances zsim will crash. I checked the crash point, it's in one vector inserting that created by the [S 0] thread. So it sames that the structures created by init.cpp can not be touched by the second instance.
detail info is as follow:
