Is garbage collection turned on? If not, the problem here is most
likely that your "mstr" variable is pointing at a string that has
already been released (you should do [[NSMutableString alloc]
initWithString:@"Alabama"] or -retain the result of the -
stringWithString: call).
Kind regards,
Alastair.
