No, a stack overflow isn't a failure to allocate more space on the stack, it's writing more data to a variable on the stack than what had been allocated for it. For example, if you declare an array for 10 characters, then write 30 characters to it, it's a stack overflow (because the variable's on the stack, and you overflowed the boundaries of it). -- Poison [BLX] Joshua M.
