Initializing local variables with dummy values takes the compiler the
chance to identify a code path were no real value is assigned by
mistake.

As far as I understand the discussion, it is not about whether the
variable is used before a value is assigned to it, as this is pretty
obviously not the case.  It is about whether the variable should be
checked for being NULL or checked for pointing to '\0' before passing
it to a printf()-like function.
