;-) In the mean time, the following code dies at the indicated line
(// DIES HERE) with a SIGSEGV / EXEC_BAD_ACCESS.
NSString * strA = [preferences objectForKey:@"contentsa"];
NSString * strB = [preferences objectForKey:@"contentsb"];
StringPtr strAPtr;
StringPtr strBPtr;
CFStringGetPascalString((CFStringRef) strA, strAPtr, 256,

Change StringPtr to Str255 in your declaration.
