_BLOCK_TYPE_IS_VALID(pHead->nBlockUse)

This is a part of the code of character's inventory system. This part will swap two inventory slots (itemslot[i][j] and highlight). They will swap array of item pointer, number of item in that slot(stack), default slot background and current slot background. It's fine when they swap for the first time, but when trying to swap back, that error occured, right after break; command.

I've googled a bit and found out this error has something to do with segment fault or memory leaks, but I have no idea which part of the code that cause this. Can anyone point out?

None of these function leads to delete or delete[], btw;

[CODE]
for(int i = 0; i< 5; i++) for(int j = 0; j< 5; j++)
{
if(itemslot[i][j]->button->Intersects(base))
{
ItemSlot slot = *itemslot[i][j];
itemslot[i][j]->stack = highlight->stack;
itemslot[i][j]->item = highlight->item;
stringstream s, s2;
s << itemslot[i][j]->stack;
itemslot[i][j]->button->SetText(s.str());
itemslot[i][j]->buttondefaultimage = highlight->buttondefaultimage;
highlight->stack = slot.stack;
highlight->item = slot.item;
s2 << slot.stack;
highlight->button->SetText((slot.stack > 0)? s2.str() : "");
highlight->buttondefaultimage = slot.buttondefaultimage;
for(int k = 0; k< 3; k++)
{
Image *img = itemslot[i][j]->button->GetImage(k);
itemslot[i][j]->button->SetImage(k, highlight->button->GetImage(k));
highlight->button->SetImage(k, img);
}
highlight = null;
break;
}
}

Ah never mind. I've fixed that. It had something to do with "ItemSlot slot = *itemslot[i][j];" or passing 2 or 3 levels pointer. Sorry.

That usually means that you try to delete something not allocated with new.

for example:
[source lang="cpp"]int a;
int* pA = &a;
delete pA;[/source]
would generate that error. Edited by SamiHuutoniemi
