// The bug happened like this:
//  1. The main binary adds an itab for *json.UnsupportedValueError / error
//     (concrete type / interface type).  This itab goes in hash bucket 0x111.
//  2. The plugin adds that same itab again.  That makes a cycle in the itab
//     chain rooted at hash bucket 0x111.

func (e *UnsupportedTypeError) Error() string {
	return "json: unsupported type: " + e.Type.String()
}

// An UnsupportedValueError is returned by [Marshal] when attempting
// to encode an unsupported value.
type UnsupportedValueError struct {
	Value reflect.Value
	Str   string
}

func (e *UnsupportedValueError) Error() string {
	return "json: unsupported value: " + e.Str
}

	}
	for _, tt := range tests {
		t.Run(tt.Name, func(t *testing.T) {
			if _, err := Marshal(tt.in); err != nil {
				if _, ok := err.(*UnsupportedValueError); !ok {
					t.Errorf("%s: Marshal error:\n\tgot:  %T\n\twant: %T", tt.Where, err, new(UnsupportedValueError))
				}
			} else {
				t.Errorf("%s: Marshal error: got nil, want non-nil", tt.Where)
