I did see a precision patch by Vitaliy fixing this problem, which was 
not applied, presumably since there is a better way to fix this.

The patch being reverted seems interesting - it basically undoes a prior 
effort to get local constants into the same namespace as global ones due 
to relative addressing. I assume this is done for performance reasons, 
is this correct ?  I see your patch is special-case disabled in the case 
of relative addressing. Do we really want to support multiple constant 
loading code paths for performance savings ?
