Bug 1167383

The error with boost-filesystem is listed as now fixed per: https://bugzilla.redhat.com/show_bug.cgi?id=1108268

However, it turns out that there is a related problem: boost-interprocess also turns out to be incompatible with devtoolset. The code to reproduce the error is as follows:

$ rpm -q boost-devel devtoolset-2-gcc-c++
boost-devel-1.41.0-25.el6.x86_64
devtoolset-2-gcc-c++-4.8.2-15.1.el6.x86_64

$ cat interprocess.cc 
#include <boost/interprocess/managed_shared_memory.hpp>
#include <boost/interprocess/allocators/private_node_allocator.hpp>

class A {};

void do_allocate(boost::interprocess::fixed_managed_shared_memory *segment) {
  boost::interprocess::private_node_allocator<
  A, boost::interprocess::fixed_managed_shared_memory::segment_manager, 1024>
    allocator(segment->get_segment_manager());
  auto* pool = allocator.get_node_pool();
  pool->deallocate_nodes(pool->allocate_nodes(10));
}

A* find(boost::interprocess::fixed_managed_shared_memory *segment) {
  return segment->find_no_lock<A>(boost::interprocess::unique_instance).first;
}

The error is also reproducible on DTS3, running
  scl enable devtoolset-3 'gcc -c -std=c++0x -Wall interprocess.cc'
with interprocess.cc as in the previous comment.

Boost shipped with Red Hat Enterprise Linux 7 can generally not be considered compatible with C++11.  That it can be compiled with system gcc in c++0x mode, but can't be with gcc 4.8, just means that the constructs that Boost uses are buggy with respect to C++11 compliance.  Similarly you could blame the system GCC that it allows these constructs to pass, which is likely a problem in its C++11 support.  These codebases were written when C++11 was not finalized yet, and these interoperability problems are to be expected.

A fix

Since bug 1170010 is considered, we should consider this one as well.

Verified for build boost-1.41.0-27.el6 and both devtoolset 3.x/2.x.

Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
resolution of ERRATA.
