# go to the innermost frame (gdb) down 100000 (gdb) set var $stack = $sp # go to the outermost frame (gdb) up 100000 (gdb) print $sp - $stack 要回答第二个问题,您需要使用调试符号构建的libpthread。如果使用GLIBC,您可以执行以下操作: # Go to frame which is `start_thread` (gdb) ...
使用bt查看当前调用栈信息(call stack,即函数调用层次信息),当前进程的是由main() -> sleep() -> nanosleep() -> __kernel_vsyscall()一层一层调入。注意“#数字”,在GDB中这叫stack frames,或直接称为frame,运行栈由一个或多个连续的frame组成,数字越小代表调用层次越深。 使用bt full查看详细调用栈信息...

We are only interested in our own code here, so we want to switch to stack frame 3 and see where the program crashed: (gdb) frame 3 #3 0x80484b2 in main (argc=1, argv=0xbffffaf4) at segfault.c:10 10 fgets(buf, 1024, stdin) ...

The recently released Gdb 7.10 added support for writing a frame unwinder in Python, which is ideal for us. doc: https://sourceware.org/gdb/current/onlinedocs/gdb/Unwinding-Frames-in-Python.html#Unwinding-Frames-in-Python The issue track...
Stack(栈) 当调试的程序暂停时,你首先想知道的是它停在了什么地方,以及它是怎样到达那里的。 调试的程序每调用一个函数,就会产生关于这个调用的相关信息。这些信息包括调用前的位置、传递的参数、以及被调用函数的局部变量。这些信息保存在一个名为栈帧(stack frame)的数据块中。栈帧是在内存中分配的成为“调用栈...
