In [live, not core-file] gdb, try this: (gdb) p pifi(pool, <index>)
Which will tell you if <index> is free (invalid) or not (valid). Also: (gdb) p pool_elts(pool) To see how many elements are in the pool. Finally: (gdb) p vl(pool) To what vec_len(pool) is. HTH...

I have a pool of some structures. custom_struct *pool; This custom_struct has alignment with 64 byte cache_line. now, I have added 3 entries in this pool. The code seems to be working fine in adding/deleting/traversing this pool using pool_elt_at_index. However, If i use gdb to view the elements using pool[0], pool[1] and pool[2], they are giving some invalid entries. The first entry pool[0] seem to be fine, but the next entry onwards are showing invalid entries in GDB. Is there anything wrong i am doing in gdb while traversing the pools ? -- Thanks & Regards, Murthy
