ifstream close出错
为什么这样写，会出现错误？？？？？？？？？
ifstream file1;
file1.open("D:\\60x55.BMP", ios_base::binary | ios_base::in);
if (!file1)
{
cout<<"error";
}

file1.seekg( 0, ios::end );
fstream::pos_type flen = file1.tellg();
file1.seekg( 0, ios::beg );

char *buf = new char(flen);
file1.read(buf, flen);
file1.close();

编译连接没问题， 但运行的时候， 会出现一个对话框，This may be due to a corruption of the heap, and indicates a bug in filectrl_test.exe or any of the DLLs it has loaded.

如果将char *buf = new char(flen);
file1.read(buf, flen);
去掉的话， 就没事，能运行。

[解决办法]
char *buf = new char[flen];
