EXC_BAD_ACCESS KERN_INVALID_ADDRESS 0x0000000000000030

This is kind of a one off exception that only happened a few times on some devices. I can't reproduce it:

Is this known?

I have not seen this one in the wild before. Do you know what attributed text is being set?

[vanniktech]

Unfortunately, not.
