fixes #23524

proc isAnalysableFieldAccess*(orig: PNode; owner: PSym): bool =
  ...
  result = n.kind == nkSym and n.sym.owner == owner and
    {sfGlobal, sfThread, sfCursor} * n.sym.flags == {} and
    (n.sym.kind != skParam or isSinkParam(n.sym))

In isAnalysableFieldAccess, globals, cursors are already rejected
