打开 Thread Sanitizer 会导致信号 SIGABRT

Question

当我从 Xcode 版本 11.3 (11C29) 和运行中创建新的单视图应用程序时，一切正常。

当我打开 Thread Sanitize 时

然后尝试运行同一个应用程序，我得到 Thread 1: signal SIGABRT

这是回溯

我是不是遗漏了一些东西，或者是没有正确使用 Thread Sanitizer。

编辑：我在 Apple 的反馈助手中打开了一个 ID 为 FB7513235 的问题。我在反馈助手中打开的票表明有类似的报告问题。

问题已在 Xcode 11.3.1

中解决

Resolved an issue that prevented Xcode from launching processes with Thread Sanitizer enabled on macOS Catalina 10.15.2. (57822138)
