12659	Deadlocked with boost::interprocess::managed_mapped_file find	soumyadutta13@…	Ion Gaztañaga	"Scenario : I have a existing file which at first is opened & loaded using
{{{
m_file.reset(new boost::interprocess::managed_mapped_file(boost::interprocess::open_or_create, file_name.c_str(), m_size));
}}}

then I am using find member function
{{{
Type *vect = m_file->find<Type>(key).first;
}}}

Here my code halts(deadlock).

If you see here onwer is 16792, but I don't see any such thread.

Some more info.
