我写的代码在C操作的文件，它解析的文本片段从文件input.txt，这里是

(
"The quick brown fox jumps over the lazy dog" is
an English-language pangram – a sentence that
contains all the letters of the alphabet. 
)
(
The phrase is commonly used for touch-typing
practice, testing typewriters and computer
keyboards, displaying examples of fonts,
)
(
The earliest known appearance of the phrase
was in The Boston Journal. In an article
titled "Current Notes" in the February 9.
)

它编译和打印文本成功，但我用这个命令来检查是否有任何泄漏

$ valgrind --track-origins=yes --leak-check=yes -s ./file-parser

型
它抱怨无条件跳转和未初始化的字节。
我已经尝试启动vgdb服务器来跟踪到底是什么导致了这些问题，

$ valgrind --track-origins=yes --vgdb=yes --vgdb-error=0 ./file-parser
$ gdb ./file-parser
(gdb) target remote | vgdb

但是我不知道该怎么做，你能建议你怎么做跟踪这些错误吗？
