9523	reserve() corrupts data in boost::bimap vector_of_relation	Artem V L <luart@…>	Matias Capeletto	"bimap::reserve() has bad behavior:
  1. Corrupts the data by inserting item into the empty bimap
  2. Reserves incorrect amount of elements capacity

Environment: Linux Ubuntu x64 3.2.0-57-generic 87-Ubuntu SMP, gcc (Ubuntu 4.8.1-2ubuntu1~12.04) 4.8.1

Code:
{{{
	typedef unsigned  Id;
	const unsigned  m_nodes = 1518;

	typedef boost::bimap<boost::bimaps::unordered_set_of<Id>,
		boost::bimaps::unconstrained_set_of<Id>,
		boost::bimaps::vector_of_relation>  Nbimap;
	Nbimap  m_nbimap;


fprintf(stderr, ""Initial bmsize: %u, capacity: %u\n"", m_nbimap.size(), m_nbimap.capacity());
	m_nbimap.reserve(m_nodes);
fprintf(stderr, ""Postreserve bmsize: %u, capacity: %u, nsize: %u\n"", m_nbimap.size(), m_nbimap.capacity(), m_nodes);
}}}

Console output:
{{{
Initial bmsize: 0, capacity: 0
Postreserve bmsize: 1, capacity: 15, nsize: 1518
