Valgrind沒有顯示行號

Question

我已閱讀了無數關於此問題的問題，並且沒有任何答案有幫助。

我不能發佈我的代碼，因爲太多了，但是我會提供我的makefile行和valgrind信息。我正在編譯gcc -std=c99 -Wall src/main.c src/filein.c src/make_game.c -g -O0 -Iinclude -o bin/rogue -lncurses。

我這個Valgrind的運行：valgrind --leak-check=full /home/pi/rogue/rogue/bin/rogue assets/room.txt

我的輸出：

這個輸出並不能幫助我的一切，我真的很感激，如果有人可以幫助。

你的輸出與其說是展示與行號而是整個回溯過短的問題，因爲它只顯示malloc()功能，但不來電。

您可以嘗試使用較新的Valgrind版本。你的版本（3.7.0）已經有幾年了，同時在ARM系統上也有了改進。
