There is no dereference of bar in the testcase.  What is there is an
address computation based on bar, that should certainly be warned on.
And I do see that warning with trunk (but not with 4.5 or 4.6, I suppose
my uninit TLC patch somehow fixed this):

$ ./cc1 -quiet t.c -Wall
t.c: In function 'main':
t.c:10:20: warning: 'bar' is used uninitialized in this function
[-Wuninitialized]

so, what is your real issue?
