My patch was put in last night (along with your find-nearest-line change), so we now 
have 16-byte alignment. The patch is safe in that just the alignment of .data and 
.text sections are changed, and the default alignment is left as-is. This means we 
don't have to make adjustments for zeroes in the .ctor and .dtor sections like 
changing the default alignment would have required.
