当到达C代码中的一行时，我试图获取回溯。
我将命令文件提供给gdb，它可以工作，除了到达断点时什么都没有发生。
我正在将Debian Testing与gdb版本9.1-3一起使用
我的代码是使用CFLAGS编译的：
-Og -g3 -m32 -gdwarf-4 -fvar-tracking-assignments -w
gcc版本是（Debian 9.3.0-10）9.3.0
使用其他版本的矮人似乎没有什么区别。
我包含的命令文件是：
set confirm off
set pagination off
set logging file gdbrogue.txt
set logging overwrite on
set logging on
set breakpoint pending on
#set trace-commands on
directory /home/me/src/github/rogue-54-for-rogomatic
symbol-file -readnow /usr/local/bin/rogue

if ($current->t_dest > 0)
printf " t_dest->y %d t_dest->x %d\n", $current->t_dest->y, $current->t_dest->x
end
set $current = $current->l_next
end
end
break chase.c:32 if (level == 7)
commands
printf "player(y,x) (%d,%d)\n", player.t_pos.y, player.t_pos.x
my_prt_mlist
end
break chase.c:455 if (level == 7)
commands
printf "player(y,x) (%d,%d)\n", player.t_pos.y, player.t_pos.x
my_prt_mlist
backtrace full
end
while (level < 7)
next
end
while (level == 7)
step
end
while (level > 7)
next
end
输出显示已达到中断，但未显示回溯？
roomin (cp=0x582403cc) at chase.c:445
445 roomin(coord *cp) {
452 if (((cp->x > MAXCOLS) || (cp->y > MAXLINES)) ||
454 msg("in some bizarre place (%d, %d)", unc(*cp));
Breakpoint 2, roomin (cp=0x582403cc) at chase.c:455
455 return NULL;
do_chase (th=0x5823ede0) at chase.c:142
142 door = (chat(th->t_pos.y, th->t_pos.x) == DOOR);
任何想法我在这里做错了还是这是gdb / gcc错误？
我一直在寻找类似的问题和答案，但似乎没有一个特定的问题。
谢谢！ ：）
好吧，在经过各种尝试和阅读之后，我终于至少得到了上述脚本的修改版本才能工作。似乎nexts和steps的while循环会覆盖对输出的任何询问。当我最后删除循环时，将显示清单和回溯。
