I have a lot of trouble with string variables becoming
"invalid" according to their value in the Debugger. If I set a
string variable like NSString *str = [NSString

but then when I try to use it later in the program it is invalid and
crashes the program. Ususally even tho' the address for the string
is the same as before.
