           Summary: repeated structure declaration crashes clang
           Product: clang
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: AST
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: nunoplopes at sapo.pt
                CC: llvmbugs at cs.uiuc.edu

The following code crashes clang:

void foo() {
  struct xpto;
  struct xpto;

The crash happens because both stmts point to the same decl. When destroying
the stmts, both will free the same decl, and thus crashing.
This may get fixed with Ted's proposal for struct stuff, but here's one more
test case.
