True.

That's why #gccbug went the safe route, took the cost of extra instructions, and initialized it to zero.


uninitialized_var() has the advantage that it generates no code, whereas "=
0" often adds instructions.  Plus of course it is self-documenting, 
greppable-for
and centrally alterable.

Agreed.
