关于std :: string中可能存在内存泄漏的许多valgrind警告我遇到了问题,如下所示:

120 bytes in 4 blocks are possibly lost in loss record 4,192 of 4,687
    at 0x4A06819: operator new(unsigned long) (vg_replace_malloc.c:230)
    by 0x383B89B8B0: std::string::_Rep::_S_create(unsigned long, unsigned long, std::allocator<char> const&) (in /usr/lib64/libstdc++.so.6.0.8)
    by 0x383B89C3B4: (within /usr/lib64/libstdc++.so.6.0.8)
    by 0x383B89C4A9: std::basic_string<char, std::char_traits<char>, std::allocator<char> >::basic_string(char const*, unsigned long, std::allocator<char> const&) (in /usr/lib64/libstdc++.so.6.0.8)

我在想:

• std :: string(GCC 4.1.2)使用任何内存池吗？
• 如果是这样,有没有办法禁用池(以调试版本等形式)？
