Bizarre Seg Fault

[csjay]

I'm using a simple linked list class and have found that the delete statement is causing a seg fault- the program using it periodically calls the clear function, and on certain inputs the program crashes at the delete statement. I have no idea what is causing it and would appreciate any suggestions~

bool clear()
{
bool isCleared=false;
Node * curNode=Head;

if(Head != NULL)
isCleared=true;

while(curNode != NULL)
{
Head=curNode->next;
delete curNode; <-------
curNode=Head;
}
curNode=NULL;

CurPos=-1;
SizeOf=0;
Current=NULL;
Head=NULL;
Tail=NULL;

return isCleared;
}

It may be impossible to tell from what you have posted, but a wild guess would be that if some of your other code could ever cause the condition curNode == curNode->next i think you would see the behavior you describe.
