            Bug ID: 52066
           Summary: Failure to optimize out dead store when address is of
                    one of two unused locals
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Scalar Optimizations
          Assignee: unassignedbugs at nondot.org

int foo(bool c)
{
  int a, b;
  return *(c ? &a : &b) = 0;
}

This can be optimized to `return 0;`. This optimization is done by GCC, but not
LLVM.
