I've just had a crash in CGImageSourceCreateThumbnailAtIndex( new_image, 0, imageOpts ); The new_image and imageOpts were created/assigned just a few lines earlier in the code. (and in the debugger they appear to be non-null.)
So I was wondering if CGImageSourceCreateThumbnailAtIndex() is thread-safe. Maybe, it would be more correct to ask whether the CGImage framework is re-entrant. The only other CGImage functions I am using, as far as I can see, are CGImageRelease() and layer.content = image. (The latter is not directly a CGImage function, but it might use them.) These two functions might get called in a different thread - but, of course, never on objects I pass into CGImageSourceCreateThumbnailAtIndex() ! Any ideas as to why I am experiencing the crash, will be appreciated. Best regards, Gabriel
