【问题描述】：
我在使用 Valgrind 来检查内存泄漏时遇到了一些问题（也为了理解我在 fprintf 中遇到的段错误），但似乎不知何故使用了一些未初始化的值，这些值不是来自我的代码。 我是使用调试器调试的新手，所以我可能会遗漏一些东西。
我知道 Valgrind 不适合我的默认 GCC OpenMP (http://valgrind.org/docs/manual/drd-manual.html#drd-manual.openmp)，但我正在使用它并使用 -pedantic -Wall -static -O0 -g -fopenmp 编译我的代码我没有收到任何错误。
但是，当使用 Valgrind 运行时
valgrind --leak-check=full --track-origins=yes --error-limit=no --log-file=./logfile ~/developing/trunk/gop.exe
我的日志文件中有很多以
开头的警告==5944== Memcheck, a memory error detector

然后收到很多类似于下面的警告（数千个！）

==5944== by 0x498920: (below main) (libc-start.c:146)
我在编译或运行 Valgrind 时是否遗漏了什么？还是我的代码真的有所有这些错误？
非常感谢！
