Typo in .vue template causes stuck?

[wyhooo]

I'm on: macOS v10.12.2, node v6.9.1, npm v3.10.10, webpack v1.14.0, vue-cli v2.8.0.
I used vue-cli to build a project with eslint disabled.

There was a typo in my HTML code:
<template>
...
<div class="swiper-slide" v-for="data in swiperData">
<a v-bind:href="data.link"><img v-bind:src="data.img">< /a>
</div>
...
</template>

Note a space was inserted in the </a> tag.

After I ran npm run dev the terminal stuck at "Compiling...". About 30 seconds later the temperature and fan speed of my Mac was out of control. Then I killed the node process.
That occurred every time I ran npm run dev or npm run build until I found the typo in my .vue component.
Does anyone know the reason why it happens? Thanks in advance.

Missed one thing: if I disabled all style loaders the above things won't happen.

This is probably something that has to be addressed in the vue-loader repository, not here
