Thread: Error from vector push_back()

Hi

I am trying to add an element to a vector with this code:

Code:

//newMaterial is initted here a bit above:

tMaterial newMaterial = {0};

//Here is the push_back function

pModel->numOfMaterials++;
pModel->pMaterials.push_back(newMaterial);
memset(&(pModel->pMaterials[pModel->numOfMaterials - 1]), 0, sizeof(newMaterial));

The first element that I add works fine, but the second makes the program crash with this error (in MSVC 7):

Debug error!

DAMAGE: after normal block (#53) at 0x003DF6C0

I have a similar function that looks like this, and as far as I know it doesn't crash after more than one object:

Code:

tDobj newObject = {0};

pModel->numOfObjects++;
pModel->pObject.push_back(newObject);
memset(&(pModel->pObject[pModel->numOfObjects - 1]), 0, sizeof(newObject));

Anyone know if there's anything wrong here, or do I need to post more code?

Thanks in advance

Edit:

Here is the declaration of those vectors:

Code:

	vector<tDobj> pObject;
	vector<tMaterial> pMaterials;
