if you align the mutable pointer, you don’t need to separately align a const 

Of course one can alter code by aligning a mutable pointer first and then converting it to a const pointer, instead of first converting it to const and then aligning the result. But that might not be convenient. The part of the code that needs alignment might have access to only the const pointer, and should be able to align the const pointer on its own without bothering the part of the code that doesn't need alignment.

Anyway, we're getting a long way from the original bug report. I'll let you have the last word on this tangential topic, if you like.
