The boost smart pointers can be copied without problems, so this
shouldn't cause any corruption. Building on the small example I was
doing before, the following works without problems:
{
RWMol *m=new RWMol();
m->addAtom(new Atom(6));
m->addAtom(new Atom(6));
m->addBond(0,1,Bond::SINGLE);
ROMOL_SPTR msp((ROMol *)m);
RDKit::MOL_SPTR_VECT m_vF;
m_vF.push_back(msp);
ROMol *nm = new ROMol(*m_vF[0]);
m_vF.push_back(ROMOL_SPTR(nm));
RDKit::MOL_SPTR_VECT m_vF2;
m_vF2.resize(m_vF.size());
std::copy(m_vF.begin(),m_vF.end(),m_vF2.begin());
std::cerr<<m_vF2[0]->getNumAtoms()<<std::endl;
}
The original error you saw, from here:

is triggered when you try to dereference a smart pointer that has a
null pointer as its contents. I'd suggest being sure that your
original vector doesn't have any empty elements (cases where the
molecule was a null pointer).
