为什么这个代码并不会导致内存泄漏？

int iterCount = 1000;
int sizeBig = 100000;
for (int i = 0; i < iterCount; i++)
{
   std::auto_ptr<char> buffer(new char[sizeBig]);
}

当我试图使用pycparser注释解析文件时,我得到了ParseError

import pycparser
parser = pycparser.CParser()
parser.parse("int main(void){return 0;}")
parser.parse("/* comment */ int main(void){return 0;}")


Traceback (most recent call last):
File "test_pycparser.py", line 18, in <module> parser.parse("/* comment */ int main(void){return 0;}")
File "build\bdist.win32\egg\pycparser\c_parser.py", line 124, in parse

解决方案:pycparser在当前版本中不支持源代码中的注释,但是这个fork允许它,或者您可以使用来自问题Python片段的配方来删除C和C++注释以从源代码中删除注释.
