Question

我正在运行多线程程序。我正在尝试使用远程调试来调试它。我已将进程附加到gdb并在代码中设置断点，以便断点在位置（动态类似于库中存在的断点位置）命中，但在动态链接库中创建新线程后应用程序崩溃码。

我在RTOS上运行此应用程序

(gdb) info threads
[New Thread 1807]
[New Thread 1808]
[New Thread 1812]

(gdb) n

(gdb) n
Program received signal SIGABRT, Aborted.

0x00007ffff68643f7 in raise () from /lib/libc.so.6
(gdb) n

使用RTOS在多线程应用程序中命中断点后，使用gdb进行进程崩溃
