【问题描述】：
要调试一个使用 PIN 工具的模拟器，通过使用 2 个不同的终端窗口，我执行以下操作：
/home/agy/mcsim/pin/intel64/bin/pinbin -pause_tool 5 -t /home/agy/mcsim/Pthread/mypthreadtool -port 47145 -skip_first 10000 -- McSim/JacNoBoost/JACCARD
Pausing to attach to pid 5465
To load the tool's debug info to gdb use:
add-symbol-file /home/agy/mcsim/Pthread/mypthreadtool 0x7f86e6c06ee0 -s .data 0x7f86e709f620 -s .bss 0x7f86e70aaac0
在另一个窗口中，我执行以下操作：
gdb /home/agy/mcsim/Pthread/mypthreadtool

Continuing.
在某些时候，pin tool 冻结，我手动向 pin tool 发送中断信号并尝试在附加的窗口上对其进行调试。为了了解在哪一行 pin 实现卡住，我尝试了 backtrace 命令，但即使添加了符号文件，它也会返回问号。
Program received signal SIGINT, Interrupt.

我在这里找不到错误的方法。你能帮帮我吗？

Agy，你能确认你看到的地址在 pin 工具/pin 里面吗？执行
cat /proc/<pid>/maps并使用 pin 和 pintool 交叉引用这些地址范围。
