[Bug tree-optimization/19651] New: [4.0 Regression] Confusing warning about uninitialized variable

[ian at airs dot com]

When I compile the attached C++ test case with mainline with the options -O3 -W,
I get the warning:

/home/ian/foo1.cc:29: warning: ‘sv$a$1’ is used uninitialized in this function

I think it is trying to give me the useful warning that sv.a[1] is
uninitialized, which it is.  However, using the bogus name sv$a$1 is more
confusing than useful.

I get no warning from gcc 3.4.2
