re PR tree-optimization/91010 (ICE: Segmentation fault (in location_wrapper_p))
PR tree-optimization/91010
* tree-vect-stmts.c (scan_operand_equal_p): If offset1 == offset2,
return true. Otherwise, don't call operand_equal_p if offset1 or
offset2 is NULL and just return false.
* g++.dg/vect/simd-10.cc: New test.
