The `FIXTURE(args)` macro defines an empty `struct _test_data_args`, leading to `sizeof(struct _test_data_args)` evaluating to 0. This caused a build error due to a compiler warning on a `memset` call with a zero size argument.

Adding a dummy member to the struct ensures its size is non-zero, resolving the build issue.
