chxj19 commented on issue #900: 如何在bthread_mutex_t死锁问题时查看bthread的堆栈 URL: https://github.com/apache/incubator-brpc/issues/900#issuecomment-524751456 非常感谢，刚刚我试了一下，可以看到死锁bthread的堆栈信息了。 但是有部分的bthread frame出现了如下的报错： ``` (gdb) bthread_frame 4 Python Exception <class 'gdb.MemoryError'> Cannot access memory at address 0x8: Error occurred in Python command: Cannot access memory at address 0x8 (gdb) bt #0 0x0000000000922b0b in jump_stack (to=<optimized out>, from=<optimized out>) at /root/incubator-brpc-0.9.5/src/bthread/stack_inl.h:129 #1 bthread::TaskGroup::sched_to (pg=0x0, next_meta=0x7ffd67ea77f0) at /root/incubator-brpc-0.9.5/src/bthread/task_group.cpp:601 (gdb) bthread_frame 5 Python Exception <class 'gdb.MemoryError'> Cannot access memory at address 0x8: Error occurred in Python command: Cannot access memory at address 0x8 (gdb) bt #0 0x0000000000922b3f in bthread::TaskGroup::sched_to (pg=0x0, pg@entry=<error reading variable: Cannot access memory at address 0x8>, next_meta=<error reading variable: Cannot access memory at address 0x8>) at /root/incubator-brpc-0.9.5/src/bthread/task_group.cpp:626 Cannot access memory at address 0x8 ``` 看上去像是计算地址时出现了一点问题？
