  The compiler's internal state may become inaccurate if a
  L1-digit value is first moved to L1-digit data item and then
  moved a L2-digit SIGN LEADING SEPARATE CHARACTER data item,
  where L1 > L2.
  When the compiler detects that its internal state is
  inaccurate, it abends.
  

Problem conclusion

• The compiler was fixed to update its internal state correctly.
