     John: xcalloc() does require its second argument to be positive, please see
     the details in the commit message above.


In that case, we seem also to have the same issue in the following
places:

     
return xcalloc (sizeof (unsigned long int), DIV_RND_UP (n, BITS_PER_ULONG));
./src/libpspp/bit-vector.c:28

struct fmt_guesser **fg = xcalloc (sizeof *fg, n_vars);
./src/ui/gui/psppire-import-assistant.c:1244

struct value_node **nodes = xcalloc (sizeof *nodes, n_vals);
./src/math/categoricals.c:483
