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.
