Summary: If you create CFAttributed string with base text "新幹線k" and a Ruby annotation "foo", create a CTLineRef from that, and call CTLineGetImageBounds() on the CTLineRef, the call to CTLineGetImageBounds() crashes with EXC_BAD_ACCESS. If you remove base text consists of either all Kanji characters, or all Roman characters, no crash occurs. Steps to Reproduce: I have verified this under Mac OS 10.10.5 using Xcode 6.4. 1. Open the Xcode project in the attachment. 2. In Xcode, do Product > Run 3. Examine the Xcode debug panes. Expected Results: The output pane contains information from printf, detailing the typographic and image bounds of Ruby-annotated text created in the test program. Actual Results: The test program crashes in a call to CTLineGetImageBounds() with EXC_BAD_ACCESS. Version: Mac OS 10.10.5
