I am having similar problems, only there are no shared pointers
involved.  I was getting this segv also, but as I pared the example
down and it mutated into a memory corruption problem:

    *** glibc detected *** ./serio: double free or corruption (fasttop): 0x0805c5c8 ***

    ./serio(__gxx_personality_v0+0x69)[0x8053c41]

The problem I'm experiencing only seems to occur when the class
implementation is in a shared library.  I have attached a simple
example that reproduces the bug.

My system details are:

    Intel i686 cpu
    Ubuntu Hardy Heron
    g++ (GCC) 4.2.3 (Ubuntu 4.2.3-2ubuntu7)
    libstdc++6-4.2-dev  4.2.3-2ubuntu7 
    Boost 1.36.0
    ./configure --prefix=/home/mecklen/work/boost-install \
	--without-libraries=python \
	--without-icu --without-mpi

This is a real show-stopper for us.  Any help would be greatly
appreciated.

Thanks,
