 The method runtime_sized_ringbuffer::pop(T*, size_type) when used with
 interprocess allocator produces the following error when compiled with g++
 4.9.1 under linux:

 to ‘int*’

 I have attached a small test to reproduce the problem and a patch, but
 other method seems to suffer from the same problem.
