Porting from VC6 to Linux Fedora core 5 problem

[g4j31a5]

Hi, I'm a new member in the forum. I have quite a problem here. Actually, I've posted it in www.cprogramming.com, but since I needed it to be resolved fast, I post it here also.

Recently, I ported my codes from Visual C 6 to Linux. But, what I meant about porting was only copy-pasted the entire code to a new KDevelop C/C++ project (also a little letter-case correction in the #include line ). The code was successfully compiled and built. But when I run it, there's a memory corruption error. I don' tknow what's wrong with it because it never happened before in VC6. The error was in the "myVector.push_back(mObject) ". And the myVector declaration was "vector<*MyObject> myVector". The strange thing was not all of the push_back methods was faulty. Only a few of them. And it gets more strange because when I moved the faulty method to the beginning of the function, it worked fine until the next push_back method. Here's the error message:

*** glibc detected *** ./mattinggame: malloc(): memory corruption:
0x09f67f70 ***

BTW, I've changed the code into MyObject **mObject and the object was created by :"mObject = new MyObject[mCount]". It worked fine until a while. When I uncommented a large part of the code, it gone berserk again.

Can anybody help me here?? I'm desperate to a suicidal point here (well, maybe suicidal is a bit too much, but it sure give me a nightmare). Thanks in advance.
