invalid NSStrings?

Subject: invalid NSStrings?

Folks, 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 stringWithString:<some other string variable>] it seems OK initially 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. Also, I have a simple class containing 3 string variables and an integer. Then I instantiate different members of this class and save their addresses in an NSMutableArray. When I call up these objects and retrieve their string variables, it works the first time I do it, but a second attempt later to call up these class members and read the string variables always fails, because the strings are invalid. Retrieving the integer always works OK.

    . Thanks for any help

    Using Xcode 2.4 with OS 4.11.
