Valgrind 不显示行号

Question

我已经阅读了无数关于此的问题，但没有一个答案有帮助。

由于代码太多，我无法发布我的代码，但我会提供我的 makefile 行和 valgrind 信息。

我正在使用gcc -std=c99 -Wall src/main.c src/filein.c src/make_game.c -g -O0 -Iinclude -o bin/rogue -lncurses进行编译。

我用这个运行 valgrind：valgrind --leak-check=full /home/pi/rogue/rogue/bin/rogue assets/room.txt

我的输出：

这个输出对我没有任何帮助，如果有人可以提供帮助，我将不胜感激。

您的输出并没有显示行号的问题，而是整个回溯太短了，因为它只显示malloc()函数而不是调用者.

您可以尝试使用更新的 Valgrind 版本。您的版本 (3.7.0) 已经有几年的历史了，同时在 ARM 系统上的回溯也有所改进。
