stage2 build failure

For two weeks bootstrapping gcc does not work anymore for me since -Werror
is used.  The problem appears in stage 2, the previous stage works.  This
is on Fedora 44 with gcc 16.1.1:

/home/drepper/gnu/gcc/gcc/tree-vect-stmts.cc: In function ‘bool
vectorizable_load(vec_info*, stmt_vec_info, gimple_stmt_iterator*,
slp_tree, stmt_vector_for_cost*)’:
/home/drepper/gnu/gcc/gcc/tree-vect-stmts.cc:10408:47: error: ‘stride_step’

      |

/home/drepper/gnu/gcc/gcc/tree-vect-stmts.cc:10156:25: note: ‘stride_step’

      |                         ^~~~~~~~~~~


This seems legit.  Since this is the trunk version I have filed a bug.
Should I?
