Thanks for the bug report. It has been puzzling for me as well. It seems there is some duplicate entry in the expression list for the very long initializer. The duplicate entry first show up after the expand_symbol phase. The bug will disappear if the list is sorter. I have narrow it down to the sort_list() function. If we turn on " #define PARANOIA" in sort.c. Sparse can trigger assert fail: sparse: sort.c:89: verify_seq_sorted: Assertion `cmp (a, b) <= 0' failed. Aborted (core dumped) Still need more work to fix it.
