           Summary: clang c++ bad codegen with const reference?
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: sharparrow1 at yahoo.com

#include <cstdio>
struct a { int a : 10, b : 10; };
static a x;
const int &y = x.a;
int main() { x.b = 100; printf("%d\n", y); }

As far as I can tell, this is supposed to print "0"; however, it currently
prints "102400".  Testcase written because I was curious; probably no
real-world code does this.
