Sorry for my previous message. Enabling debug flags, I had a better idea of
the problem:

/usr/include/boost/graph/kolmogorov_max_flow.hpp:115: [...] Assertion
`m_rev_edge_map[m_rev_edge_map[*ei]] == *ei' failed.

So, I add in my code:

    rev[p_reverse.first] = p.first;
    // ...
    rev[p2_reverse.first] = p2.first;

It seems now to work correctly.
Thanks for your help.

Regards,

Olivier
