Core Dump when download already found

[tbremer]

Install seems to be failing only when PhantomJS has already been downloaded, if I remove /tmp/phantomjs the install works fine.

I am sure this isn't all the information you need, but please let me know what else I can provide…

Error log dump below:

npm install phantomjs-prebuilt
npm WARN install Couldn't install optional dependency: Unsupported

> phantomjs-prebuilt@2.1.3 install ~/node_modules/phantomjs-prebuilt
> node install.js

PhantomJS not found on PATH
Download already available at /tmp/phantomjs/phantomjs-2.1.1-linux-x86_64.tar.bz2

hmmm...the error message says "Allocation failed - process out of memory". i don't think this is related to anything this package is doing -- AFAIK we don't use a meaningful amount of memory.

This bug npm/npm#3340 seems to suggest it's an NPM problem?

Do you have any special flags or npmrc configs around memory settings? Maybe ask NPM-team?

I encounter this error as well.

This seems related to the MD5 computation here: install.js#L479.
On my machine, the following script forces the Node process to allocate more than 600 MB:

const md5 = require('md5');
const file = require('fs').readFileSync('/tmp/phantomjs/phantomjs-2.1.1-linux-x86_64.tar.bz2');
md5(file);

The md5 module looks unsuitable according to this issue: pvorb/node-md5#22.

Thanks for creating a PR @connesc, thanks for mergin @nick.
