PR tree-optimization/92241
* tree-vect-loop.c (vect_fixup_scalar_cycles_with_patterns): When
we failed to update the reduction index do not use the pattern
stmts for the reduction chain.
(vectorizable_reduction): When the reduction chain is corrupt,
fail.
* tree-vect-patterns.c (vect_mark_pattern_stmts): Stop when we
fail to update the reduction chain.
* gcc.dg/torture/pr92241.c: New testcase.
