illegal hardware instruction (core dumped) on importing gcloud

[wingedrhino]

I have a laptop running a Penryn CPU (Intel T4400), Fedora 21 x86_64 and Node.js installed from the official repositories (currently v0.10.33).

The only line of code in my app is:

var gcloud = require('gcloud');

And this happens:

zsh: illegal hardware instruction (core dumped)  node gcloud.js

PS: This is different from #424 because it happens on a different machine. Infact #424 happened after I attempted to run the code on a different machine (i.e, google compute cloud).

Hmm, strange. Have you seen this error before with other modules? I've heard of this issue happening with strange hardware like Raspberry Pis. Considering I don't have access to your hardware, which looks like the issue here, I'd suggest compiling NodeJS from source if you can, preferably the latest version (0.12.0) and if you cannot do that I'd look into whether https://github.com/Voxer/sse4_crc32 (a library we use in this module) is the culprit here. Perhaps try installing and using that module on its own and seeing if you run into any issues similar to the one you've listed here.

Edit: Another library worth messing with: https://github.com/broofa/node-uuid

Looks like this happened because of sse4_crc32.

Setup:

npm install sse4_crc32

Script

console.log('Importing sse4_crc32');
var SSE4CRC32 = require("sse4_crc32");
console.log('invoking sse4');
var output = SSE4CRC32.calculate("my string");
console.log('invoked sse4. output below');
console.log(output);
console.log('end');

Output

Importing sse4_crc32
invoking sse4
zsh: illegal hardware instruction (core dumped)  node require-test.js

Similar test with node-uuid created no problems.

I raised an issue sse4_crc32's repository.

So sse4_crc32 3.0.0 now has software fallback so maybe we should use it instead of the fast-crc library. Might not eliminate this issue but will help reduce the number of layers between our library and the library at hand.

Flawed fallback detection filed here: https://github.com/Voxer/sse4_crc32/issues/24

@ryanseys SSE4_CRC32 release v3.1.0 fixes hardware detection issues. I've tested it on my macbook and our SmartOS boxes and it works just fine. Feel free to upgrade your dependencies and try again.

@mahtuag Can you confirm that the latest version in master no longer gives you the illegal hardware instruction (core dumped) issue? Thanks!

[wingedrhino]

@ryanseys Sorry about the delay. Issue is still reproducible.

[anandsuresh]

@mahtuag I'm guessing you're compiling using GCC since you're running Linux. What version of the compiler are you using?

Also, can you please paste the build log in this thread?

Thanks

[ryanseys]

You can rebuild your dependencies using npm rebuild.

@anandsuresh @ryanseys rebuilding did not seem to help. Next I re-installed gcloud and it pulled in recent changes. Issue is gone now.
