The reason is the above 'fd = -1' already gone:
188 ASSERT_OK_PTR(strstr(log_buf, "R0 !read_ok"), "bad_log_0"); 189 ASSERT_LT(fd, 0, "bad_fd"); 190 if (fd >= 0) 191 close(fd); 192 193 free(log_buf); 194 }

There are more redundant 'fd = -1' in function bpf_btf_load_log_buf(), you may want to remove them as well.
