I think this is caused by a compiler bug, that can be safely ignored.
The lines in question are similar to:
GSI_MAP_CLEAR_KEY(node);
And for the case GSI_MAP_KTYPES = GSUNION_PTR this is defined as:
#define GSI_MAP_CLEAR_KEY(node) GSI_MAP_WRITE_KEY(map, &node->key,
(GSIMapKey)NULL)
And GSIMapKey is a union that contains in that case void* as a possible
type. I don't understand why NULL isn't detected as belonging to that
type, but you could try to add another type cast to the line above and
see that gets reported.
#define GSI_MAP_CLEAR_KEY(node) GSI_MAP_WRITE_KEY(map, &node->key,
(GSIMapKey)(void *)NULL)
Or rather use (char*)? I really don't see what goes on in the compiler
to complain here.
