However info_out_entry_ptr is only NULL in the first iteration of the while loop and in this case info_in_entry_ptr is also NULL (as indicated by the comment /* If info entry is null - this is the first table built */ -> this is a false positive. Nevertheless we add a check for info_out_entry_ptr to silence this warning and make it more robust in regard to code changes.
