VMWare-Ubuntu 16.04 编译器(Ex: GCC, clang, VC++...)+目标环境(跟开发平台不同的话需列出) gcc 问题(Question)： 各位板友大家好， 刚刚随意开一个新的QDialog专案，没有新增任何程式码， 直接於command line输入「valgrind --tool=memcheck --leak-check=full ./Test」.. 视窗程式出现後再将之关闭，分析结果出现一堆错误.. -- (上略) ==7722== 3,928 bytes in 1 blocks are definitely lost in loss record 7,377 of 7,430 ==7722== at 0x4C2FB55: calloc (in /usr/lib/valgrind/vgpreload_memcheck-amd64-linux.so) ==7722== by 0x1B032FBD: ???
