Anonymous class with static crashes compiler in ES2015 target

[mihailik]

TypeScript Version: npm typescript@next 2.1.0

Code

(class { static x = 0; })

Expected behavior:

Not crash compiler

Actual behavior:

Crashes during compilation:

***>node ***\typescript\lib\tsc.js cl.ts -t ES2015
***\typescript\lib\tsc.js:36955
                throw e;
                ^

This could be related to #9969 Support emitting static properties for classes with no name

Also note that #9969 seems to imply polluting the global namespace with mangled variable names in ES2015 mode. I was trying to test that, and stumbled upon the crash.

Looks like a duplicate of #9966. Could you try using the very latest tsc (node node_modules/typescript/lib/tsc.js --version should be Version 2.1.0-dev.20160729)?

Absolutely true, thanks @Andy-MS -- it is indeed a duplicate, and the latest 20160729 fixes it.

Yes, the global scope is polluted — but I can see you've opened a separate issue, thanks! 👍

BTW, I didn't realise using that thumbs-up icon closes the issue. But nevermind, it's a duplicate and needs to be closed anyway.
