glibc - Linux

我自己寫的包含自訂class的c++程式，test_file
執行到new該class時，會發生memory error

Error msg如下：

*** glibc detected *** ~/test_dir/test_file: malloc(): memory corruption:

已經終止

-------

我的情況是
class myclass{
myclass(char *filename){ initialize(filename); }
void initialize(char *filename){
cerr << "error!" << endl; // 這行也出不來
...
}
};

...

int main(){
myclass *a;
a = new myclass(fn); => 顯然是在這行就出錯了
}

非常詭異的是，同樣的檔案，改成不同檔名就能吃
WHY?
