--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This testcase started to ICE (segfault) with r248909,
cc1plus.252763: internal compiler error: Segmentation fault
0x1192507 crash_signal
../../gcc/toplev.c:341
0xde94b5 handled_component_p
../../gcc/tree.h:4450

0xdf9ab5 fold_stmt_1
../../gcc/gimple-fold.c:4405
0xdfacac fold_stmt(gimple_stmt_iterator*)
../../gcc/gimple-fold.c:4733
starting with r252764 it instead ICEs:
pr83857.C:15:1: internal compiler error: in vect_get_num_copies, at
tree-vectorizer.h:1088
and finally starting with r256126 it ICEs in exact_div, but in the same spot:
pr83857.C:15:1: internal compiler error: in exact_div, at poly-int.h:2139
0x15189bc vect_get_num_copies
