What's bothering me a lot more is the use of an appendByte: method. NSMutableData doesn't document the existence of such a method. I'm not sure why this would cause guard_malloc to choke *later on*, but it's certainly something to look at.

D'oh; I forgot I have a category for that too in NSMutableData:

- (void)appendByte:(u_int8_t)aByte
{
        [self appendBytes:&aByte length:1];
}

A traceback would be good, too. Is the guard_malloc error in the OP's function, or in Apple's code somewhere?


It's in my method. As I tried to point out, the crash occurs when trying to set returnArray[0] to the mutableBytes of the data.
