I think that (once again from the user POV) the "Principle of Least  
Surprise" should apply here - meaning that this behavior should never  
be on by default.

It is interesting that in GCC documentation for -fmerge-all-constants  
you find this:
"Languages like C or C++ require each non-automatic variable to have  
distinct location, so using this option will result in non-conforming
