New description:

 There is a possible error in the source file vrp_master_functions.c on
 line 74:

    pos = ((int)ed0 - (int)g->edges)/sizeof(edge_data) + 1;

 Casting a pointer to int works fine on 32-bit platforms, but it might be
 the case that on some 64-bit platforms an int is still 32-bit wide while a
 pointer occupy 64-bits. Thus, I would change
 that line to:

    pos = ((long)ed0 - (long)g->edges)/sizeof(edge_data) + 1;
