Re: [Boost-users] Boost Pool - error: segmentation fault

Thanks a lot. The object_pool approach doesn't work; it causes also a segmentation fault.
The option of explicitly allocating the object does work fine.
Make sure you use a recent compiler and Boost. I have seen pool 
segfaulting on some not-so-old platforms, especially with pool_allocator 
being used with nested containers. I found out that with Boost 1.34.1, 
g++ 4.3.0 and MSVC 9.0 all works fine.

For example the following segfaults with g++ 4.2.2 + boost 1.32:

#include 
#include <vector>
#include <map>

using boost::pool_allocator;
using namespace std;
int main() {
   typedef vector v1;
   typedef map v2;
   v2 m;
   m.insert(make_pair(0, v1())); // SEGFAULT with g++ 4.2.2 + boost 1.32
                                 // OK with g++ 4.3.0 + boost 1.34.1
   return 0;
}

It's probably some incarnation of the "static initialization order 
fiasco", but I did not take time to track down the exact problem with 
4.2.2 yet.

HTH,
