This bug is not a bug.  We are actually matching G++'s behavior.  From the C++
spec (3.4.5.3):

"A name having namespace scope (3.3.5) has internal linkage if it is the name of
...
 - an object or reference that is explicitly declared const and neither
explicitly declared extern nor previously declared to have external linkage "

This is exactly what we are getting.  The optimizer is just deleting the (often
dead) constant global.
