如何在Qt Creator中「設置malloc_error_break中的斷點來調試」？

Question

我QT5應用程序崩潰時，我打了關閉窗口返回：Qt Creator中4（Mac OS）中

MyApp(28741,0x7fff7aa73000) malloc: *** error for object 0x7fc40bc8e300: pointer being freed was not allocated 
*** set a breakpoint in malloc_error_break to debug 
The program has unexpectedly finished. 

如何「在malloc_error_break設置一個斷點調試」？

應該更好地通過終端在lldb/gdb中做到這一點，怎麼樣？

參考：How to find reason for app crash on close?

在斷點窗口中，右鍵點擊 - >添加斷點...變化斷點類型到功能名稱和Funcion鍵入malloc_error_break：。另一種方法是打開調試控制檯（Cmd + ）並鍵入b malloc_error_break。
