11724,managed_shared_memory constructor crash,john.saxton@…,Ion Gaztañaga,"If my system has zero shared memory available and I invoke the managed_shared_memory constructor, the constructor will crash. I am able to consistently reproduce this on Centos 6.5 using g++ 4.4.7 and Boost v1.59.

My repro case is very Linux-specific:
1: rm /dev/shm/foobar
2: dd if=/dev/zero of=/dev/shm/fill (the command will terminate once all shared memory on the system is exhausted)
3: Build the attached C++ file (I used g++ -g -I/path/to/boost/ -lpthread -lrt shm.cpp)
4: Run the resulting executable, it should crash
