Android Studio变声工程发生A/libc段错误闪退

Question

错误信息如下：
11/12 11:07:55: Launching 'VoiceChangeActivity' on Pixel 2 API 26.
$ adb shell am start -n "com.zhangpan.myvoicechange/com.zhangpan.myvoicechange.VoiceChangeActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Waiting for process to come online...
Connected to process 13038 on device 'emulator-5554'.
Capturing and displaying logcat messages from application. This behavior can be disabled in the "Logcat output" section of the "Debugger" settings page.
A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x4066 in tid 13038 (n.myvoicechange)
Process 13038 terminated.

直接运行还能打开app，但执行到中间一个按钮就闪退了．调试的时候，就是调试到某一个cpp中的一个函数就停在那里了，请高手指教。
