-initWithCString:encoding: should copy the bytes. You can verify
that yourself with a small test:
char buf[10+1] = "0123456789";
NSString *s = [[NSString alloc] initWithCString:buf
encoding:NSASCIIStringEncoding];
NSLog(@"before %@", s);
memset(buf, 'x', 10);
NSLog(@"after %@", s);
If the bytes were not copied then `before` and `after` would differ.
I don't see any memory errors in your code. My next suspect would be
memory errors in getMetadata() or getLengthOfMetadata(). Try
replacing getLengthOfMetadata(...) with pcLength=10, and/or
getMetadata(...) with memset(pBuffer, 'x', pcLength). If one of
those changes makes the crash go away then those two functions look
much more suspicious.
Sure enough, replacing those functions makes the crash go away.
Unfortunately, those functions are in a third-party library, and I
can't get around using them. I'll contact the developers of that
library and see what we can work out.
Thanks!
Hank
