[Boost-users] [Pool] pool_allocator with vector-of-vectors ??

I have a question about using the standard allocator interface in the
boost.pool library. (I'm using boost 1.34.0 with g++ 3.4.3 on redhat
linux, in case it matters.)

I've successfully used boost::pool_allocator with individual std::vector
objects, but I'm having trouble using it with a vector-of-vectors
object, like this:

  std::vector<std::vector<int, boost::pool_allocator<int> > > myvec(1);
  myvec[0].push_back(99);

The "push_back" line causes a seg-fault, which purify says is an
array-bounds-write occurring in
boost::simple_segregated_storage<unsigned long>::segregate.

Am I misusing the pool_allocator?

Thanks,
Alan
