Obfuscated script crashing when both mangled identifiers and string array are enabled.

Relevant gulp options below:

```
{
compact: true,
controlFlowFlattening: false,
deadCodeInjection: false,
debugProtection: true,
debugProtectionInterval: false,
disableConsoleOutput: true,
identifierNamesGenerator: 'mangled',
log: false,
renameGlobals: true,
selfDefending: false,
splitStrings: true,
splitStringsChunkLength: 3,
stringArray: false,
stringArrayEncoding: false,
rotateStringArray: true,
stringArrayThreshold: 1.00,
transformObjectKeys: true,
unicodeEscapeSequence: false
}
```

`stringArray` seems the culprit here. Disabling any other other primary suspects, such as `renameGlobals` and `debugProtection`, did not fix the issue. Thanks!

報告僅提供一個 Gulp 設定；先使用遭到竄改的識別碼並啟用 stringArray 重現崩潰，然後與停用 stringArray 的情況比較。未指出任何檔案、測試、輸入指令碼或錯誤輸出。完成的標準是找出並修正不相容問題，並確認該設定不再崩潰。
