如何在Qt Creator中“在malloc_error_break中设置断点来调试”？

Question

当我点击关闭窗口返回时，我的Qt5应用程序崩溃了：

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Qt Creator 4（Mac OS）中“在malloc_error_break中设置断点来调试”？

最好通过lldb / gdb中的终端来做，怎么做？

Answer 1

在“断点”窗口中，右键单击 - > 添加断点... 将断点类型更改为功能名称并键入{{1}在 Funcion：。另一种方法是打开调试器控制台（ Cmd + 5 ）并键入malloc_error_break。
