I am trying to create a boost bimap of total 177 million entries.I created a boost bimap

namespace bimaps = boost::bimaps;
typedef boost::bimap<bimaps::unordered_set_of<unsigned long long int>,
        bimaps::unordered_multiset_of<unsigned long long int> > bimap_reference;
typedef bimap_reference::value_type position;
bimap_reference reference_index_vector;

and entered the elements but it stopped entering the elements when reaching 100 million, 66 thousand entries. I would like to know if there is any maximum limit of boost bimap, or there can be some other problem.

"It stopped"? With what? My guess would be `std::bad_alloc`, meaning "I ran out of memory" – dhke Jun 29 '17 at 05:43
@dhke It did not give any message like `std::bad_alloc`. I display message on every entry and the program just got still. I work on 16 GB RAM – AwaitedOne Jun 29 '17 at 05:48
Is the program compiled for 32 or 64 bit? – zett42 Jun 29 '17 at 05:51
@zett42 its for 64 – AwaitedOne Jun 29 '17 at 05:52
Can you please verify this by printing the result of `sizeof(void*)`? – zett42 Jun 29 '17 at 05:54
@zett42 It displays 8 – AwaitedOne Jun 29 '17 at 05:59

@AwaitedOne Look at the memory consumption of your program before it "stops entering elements" - If it reaches ~16 GB, it means that you do not have enough memory to store all your entries, it it reaches ~4 GB, it might mean that you compiled a 32-bits executable. – Holt Jun 29 '17 at 08:27
@Holt Thank you, I'll check that. – AwaitedOne Jun 29 '17 at 11:03
