That implies that in fns.c:607:concat, the value of args[0], which is
the argument passed to Flength, is 35211917, a Lisp integer.

However, this makes no sense, because just a few lines above that, we
check the type of arg[0]:

  for (argnum = 0; argnum < nargs; argnum++)
    {
      this = args[argnum];
      if (!(CONSP (this) || NILP (this) || VECTORP (this) || STRINGP (this)
            || COMPILEDP (this) || BOOL_VECTOR_P (this)))
        wrong_type_argument (Qsequencep, this);
    }

So could you please check that in frame 5, argnum is indeed 0 and
args[0] is 35211917, and check the xtype of args[0] in that frame?
