* test/fiddle/test_func.rb (test_string): this test break String buffer
by `strcpy` ("000" -> "123"). However, the string literal "000" with
`frozen_string_literal: true` returns a string object from frozen
string pool. So that after this test "000" from fstring pool becomes
"123" (modified string). 'test/date/' uses "000" (as fstring) and tests
are fails (we could check with `make test-all TESTS='fiddle date'`).
* test/fiddle/test_function.rb: ditto.
* test/fiddle/test_import.rb: ditto.
