### Version 2.5.13 ### Reproduction link [https://codepen.io/anon/pen/KZyJyy](https://codepen.io/anon/pen/KZyJyy) ### Steps to reproduce Open JS console and see `[Vue warn]: Error compiling template: <div> <div v-for="testitem in testlist" > <label>{{ testitem }}</label> <input :type="inputtype" :value="testitem" v-model="testvalue"/> </div> <pre>{{ testvalue }}</pre> </div> - :value="testitem" conflicts with v-model on the same element because the latter already expands to a value binding internally (found in <Root>)` ### What is expected? Template compiled without errors, just like in Vue 2.5.3 ### What is actually happening? Errors while template compilation. On codepen this still renders component, but webpack wont build bundle because of this error. --- This code worked on 2.5.3, https://codepen.io/anon/pen/opomGr <!-- generated by vue-issues.
