That's because int is zero initialized by default and thus 
doesn't need anything more than a call to zero memory function, 
and double isn't (it is NaN), so it gets an initializer data 
blob. If you make it = 0 it might work, but even then, the 
compiler may want to reference the initializer just because 
there's a non-default init value!

It isn't a bug, this is working as designed [1]. Making it skip 
the initializer with =void or =0 explicit init values is a valid 
enhancement request though.
