           Summary: sema segfaults on conditional operator without LHS
           Product: cfe
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Semantic Analyzer
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: nunoplopes at sapo.pt
                CC: llvmbugs at cs.uiuc.edu


this makes clang segfault:
int a = 1?:3;

This is because Sema::UsualUnaryConversions() dereferences LHS (NULL) several
times.
