Hi Clark,
I had time to go back on this trouble again. My client, who has never been
able to run my app on his PPC with Leopard, sent me a new crash log. This
time I didn't use CFNumberRef but I used just NSNumber.
NSNumber *width = [NSNumber numberWithInt:(int)(size.width)];
options = [NSDictionary dictionaryWithObjectsAndKeys:
[NSNumber numberWithBool:YES], (id) kCGImageSourceShouldCache,
[NSNumber numberWithBool:YES],
(id)kCGImageSourceCreateThumbnailFromImageIfAbsent,
width,(id)kCGImageSourceThumbnailMaxPixelSize,
nil];
As I explained, this crash never occurs on Intel machines with Leopard nor
on PPC machines with Tiger. It occurs only with PPC and Leopard.
