That looks right based on what I see flashing on the keyboard there. Pasting these bytes from the Safari text field into HF can also cause an instant crash. You can't see these, now, but it will oddly display this empty input area like the entire 'nothing' is selected. But most apps today actually give me 0x08 chars, like the Safari Smart Search Field: Trust me, they are right there, you just can't see them.Įasy to witness there with Google because Google receives the chracters as part of your query. I also got 0x7F in the earlier 10.5, 10.6 days of this bug. For some reason I get 0x7F from Hex Fiend.

People who have a habit of using this key combo to clear buffers/fields have lots of strange unlucky things happen. This happens in lots of cocoa text input fields that are roughly supposed to be single-line vies of text a not multi-line ones.

Focus the left panel and repeat to, clearing that text away and it then crashing. Something gets confused in the deletion behavior while the state is kind of unstable and it seems an control character gets left behind. Hit left shift + up arrow and than press backspace/delete (in the position above the enter key) while you are still pressing the first two keys/in Hex Fiend. Hex Fiend is somewhat useful to simply demo the bug, but does not respond well compared to other apps and and crashes quickly This is an OS X bug that I've experienced on all my Macs since 10.5. I was using Hex Fiend to check up on a bug I've experienced for years and found HF to be particularly #affected.
