grunt (really uglify) fails on sha512

I tried increasing the stack trace but no luck. It keeps eating up memory an not completing.

I noticed you have your own uglify. I know infinite recursion was an issue in the upstream uglify so maybe that needs to be ported to yours?

[vibornoff]

Unfortunately I can't reproduce this bug with my node v0.10.25.
Nonetheless I see my travis build failing with node v0.11.16 exactly due to this problem.

Just updated my uglify version with the upstram. Try it now.

Note, maybe you'll have to manually reinstall local uglify-js package with rm -rf node_modules/uglify-js && npm install

I am using node v0.12.2 (via homebrew on the Mac).
Which branch do you want me to test? release or master

If I am on master and I change the package.json file:
"uglify-js": "=2.4.20",

rm -rf node_modules
npm install

grunt --with sha512

I updated uglify-js and grunt-contrib-uglify to the latest (also bumped grunt and grunt-cli but I don't think those matter). That seems to work.
"grunt --with sha512" now works.

Compression in uglify takes a long time (minutes for the above command). Disabling compression speeds it up grunt considerably. Is compression really necessary? The file is only 74KB with compression and 75KB without compression in the sha512 only case.

[ktarplee]

Disabling compression with the old uglify works as well. You can leave compression enabled if you update the uglify and the grunt-contrib-uglify modules.

About compression, @mishoo didn't approved the pull request #373 yet, so vanilla uglify-js breaks asm.js code (though it's still valid js code it doesn't pass asm.js verification and its performance dramatically degrades at least in Firefox). And that's why the compression takes so a long time.

You're right, when compression is turned off, vanilla uglify-js works fine. But it worth being turned on. With the latest patched uglify-js compressed asmcrypto.js results in 128KB vs 296KB uncompressed one.

That's why I have to maintain my own uglify-js untill @mishoo lets the patch in. You shouldn't change devDependencies in the package.json, uglify-js dependancy must be "vibornoff/UglifyJS2".

Damn, it still fails. https://travis-ci.org/vibornoff/asmcrypto.js/builds/57720786

[vibornoff]

Trying another way with bab07e1

[vibornoff]

Seems it work now https://travis-ci.org/vibornoff/asmcrypto.js/builds/60597335

I'm not sure why you closed this as your code does not work on the latest node (0.12.2).
"grunt --with sha512" is still failing unless you set mangle and compress to false in the Gruntfile
