DaveGamble#743 When the item is not the parent's first child but the parent has no children at all, cJSON_DetachItemViaPointer() unlinked the item from its neighbours and then dereferenced parent->child (NULL) to update the pointer to the last element, crashing. An item can't be detached from a parent without children, return NULL instead.
