            Bug ID: 19036
           Summary: LabelStmt cursor equality
           Product: clang
           Version: 3.4
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: libclang
          Assignee: unassignedclangbugs at nondot.org

When doing a complete tree traversal for

    int main( int, char ** ) {
        goto lbl1;
        lbl1:;
    } 

reaching LABEL_STMT via GOTO_STMT->LABEL_REF, or directly from COMPOUND_STMT,
results in cursors that are not `clang_equalCursors()`:

cursor    {kind=CXCursor_LabelStmt (201) xdata=0 data=0x0045dfac {0x00000000,
0x00900410, 0x008f2a00} }    CXCursor
    kind    CXCursor_LabelStmt (201)    CXCursorKind
    xdata    0    int
    data    0x0045dfac {0x00000000, 0x00900410, 0x008f2a00}    const void *[3]

and

cursor    {kind=CXCursor_LabelStmt (201) xdata=0 data=0x0045da74 {0x008ffed0,
0x00900410, 0x008f2a00} }    CXCursor
    kind    CXCursor_LabelStmt (201)    CXCursorKind
    xdata    0    int
    data    0x0045da74 {0x008ffed0, 0x00900410, 0x008f2a00}    const void *[3]

AFAICT this is related to "// FIXME: We end up faking the "parent"
declaration..." in CIndex.cpp
