require('gcloud') crashing on Mac

[javorosas]

My old computer and my server instance both run Ubuntu and I never had any problem at all. Recently I'm using a Mac to code and have not been able to make this module work.

How to reproduce

I started a new project to isolate the issue to a minimum. This is the content of my server.js:

var gcloud = require('gcloud');
console.log("I'm here!");

I'm using:

• A Mac with OS X 10.10.3
• Tested with gcloud@0.15.0 and 0.13.2 with same results.
• Tested with node.js 0.12.4 and 0.10.26 with same results.

Reproducing:

1. I run node server.js on the terminal
2. App crashes with the following output:

[1]    3488 illegal hardware instruction  node server.js

What I suspect

When I'm installing the npm module:

npm install gcloud@0.15

I get the following output:

npm WARN package.json testgcloud@1.0.0 No description
npm WARN package.json testgcloud@1.0.0 No repository field.
npm WARN package.json testgcloud@1.0.0 No README data

> sse4_crc32@3.2.0 install /Users/jrosas/dev/testgcloud/node_modules/gcloud/node_modules/sse4_crc32
> node-gyp rebuild

I've googled those xcode-related warnings but haven't found anything relevant. I don't know if it's related with the issue, though.

Any clues?

@abelino I might consider adding #ifdef __SSE4_2__ all over the code to deal with platform specific compilation. The code was written for our own platform (all Intel processors) which never had any of these issues. The software fallback was added way down the line. :)

@javorosas I'm running clang 6.0 on kernel 13.4 and face no issues. Can you try this on a different OS platform, like a lower kernel version? I'm trying to get my hands on an updated kernel to test at my end as well.

[javorosas]

I'm not able to try it in a different kernel version, since it's the computer from my job. But I can keep executing tests if it helps.

[abelino]

@javorosas locally can you replace the type on line 97 from uint32_t i, j, crc; to uint64_t i, j, crc; and re-run the test with all the logs.

We have quite a few of these issues popping up here that are actually coming from https://github.com/Voxer/sse4_crc32. I think since it's been almost 2 months since a reply here, this has been resolved. If not, it will probably be easier to open this up over at their repo for better, quicker help: https://github.com/Voxer/sse4_crc32.
