And I don't thing it is the best place to fix this bug in function try_split().
Why not fix it at where the ICE occurs? It is just the wrong expectation from
function dwarf2out_var_location(). Why not just look forward further if the
'prev'is not what we want? I like to add this code before gcc_assert() to fix
this issue:

       while(prev && !CALL_P(prev) && !(GET_CODE (PATTERN (prev)) == SEQUENCE
                                 && CALL_P (XVECEXP (PATTERN (prev), 0, 0)))){
          gcc_assert(NONJUMP_INSN_P (prev));
      prev = prev_real_insn (prev);
        }
