I can see stacks and heaps and so forth. But I want to store only stacks without heap. So I decided to skip anonymous mappings. Here I get in trouble. Gdb can't open that kind of core. I noticed that storing last 4 anonymous  mappings (I mean in proc maps list) solves the problem. But how can I be sure that and if the  particular mapping is vital for gdb. And what do those mappings keep.
