The SEL data formatter was working hard to ensure that pointers-to-selectors could be formatted by the same block of code. In that effort, we were taking the address-of a SEL.
This operation fails when the SEL lives in a register, and was causing problems.
The formatter has been fixed to work correctly without assuming &selector will be a valid object.
